A: Hey Bob, thanks for your question. I'm not planning to run any AppSumo campaigns in the near future. I run offers on my own site a few times a year (national holidays and following major releases). If you sign up to our newsletter you will get notified about these.
Thanks for your question. I thought they had ignored my request in the past, but actually they did grant me permission and I HAVE already implemented shallow integration with Thrive Architect. They just replied to my email and pointed that out. Please ignore my previous comments.
The shallow integration was added a few years ago, if you notice any issues with CSS / content not updating across tabs when you work in MT or publish in Thrive let me know.
Hey, I heard back from them and actually they did allow me to integrate, and I did do that already! So you should be good to go with the shallow integration, I was mistaken before.
Thanks for getting in touch. I haven't tested Microthemer with Divi 5, so I'm not sure if the shallow integration shown in the following video still works perfectly. But I am committed to supporting integration with Divi, so if you notice any issues I would be happy to troubleshoot.
Sebastian, Divi 5 is unbelievably good. I've been testing it, and it is only months away from formal release. I checked with them and they have really opened it up to developers, so you should be able to have a deep integration with Divi now. It is totally next level and is absolteuly going to blow the doors other builders, so I hope you will make MT take full advantage of its new architecture.
That's great news, I've been wanting to add deep integration for Divi for many years. Hopefully the main issue stopping me has been changed (Divi breaking out of iframes). I will most likely do this once it's passed the alpha / beta stage, as interface DOM changes can break the Microthemer integration.
Q: tier 1
hi if i buy tier 1 and use it on one site can unistall and then use it in another site?
A: Hey, thanks for your question. Licenses are not transferable between domains, so you would need a 3 or unlimited site license to use Microthemer on multiple domains. Here's an explanation for why from our FAQ page.
"The single/standard licenses permit installing Microthemer on 1/3 sites in total. So it's not possible to transfer site licenses between a rotating set of 1 or 3 domains. This is because it's a feature of Microthemer that you can completely uninstall it after making style edits, and still have the changes stick. See Microthemer's Preferences > Inactive tab for more information on that.
This is where Microthemer differs from most WP products - you don't need to keep it active on a domain in order to make use of it on that domain. As such, there would be little advantage of the developer license if the standard license allowed for domain transference.
Note: If you install Microthemer on a dev/staging domain, you can ask for it to be removed from your quota once the site is launched on the live domain. Just send us a quick message via our contact form."
Hi there, I use Oxygen Classic a lot. While I love the control, it has a couple of issues I battle with. I currently resolve these with a lot of fudging with the backend builder code and handling all CSS in stylesheets. For context, I'm obsessed with keeping my pages to under 50 kb/pageview. I'm curious if Microthemer might resolve some of these issues: * Oxygen's natural (comparatively minimal) bloat and unnecessary classes being loaded by default. It's possible to optimise and replace Oxygen.css, but not the part that ends up in universal.css. If your tool can replace that or at least create something optimisable, I'm sold. * Oxygen defaults to big > small media queries. Looks Microthemer can reverse that? On the other hand, what bloat might this add? Please be honest! Also... Will Oxygen 6 be supported, at least once it is out of beta?
Thanks for getting in touch. In answer to your questions.
- Microthemer doesn't remove CSS added by other tools like Oxygen. So it would not help with reducing the size of universal.css. - Microthemer only adds the CSS styles you create with it, and some JavaScript if you apply event based animations like inView. You can see what it adds if you visit the frontend as a non-logged in user (as an admin there are extra JS files to make the editor work of course). - Microthemer uses big to small media queries by default, although you can choose from various sets (e.g. mobile first). Whatever you choose, Microthemer would not alter the order of media queries in Oxygen. - In terms of bloat, Microthemer is considerate. It will added CSS styles that you create with it - it doesn't replace CSS. So it is additive. But it adds CSS in the most performant way it can. It loads CSS asynchronously for below the fold content (context 1400 pixels from the top of the browser). And it loads (minimal) above the fold CSS as an inline style tag by default to reduce http lookups. And it minifies CSS for non-logged in users. You should be able to use it while keeping under your 50KB goal as the render blocking above fold CSS will be minimal. - Microthemer will support Oxygen 6 at some point, but it may not be the exact moment it comes out of beta. I'm currently focusing on the AI assistant at the moment: https://themeover.com/wordpress-css-editing-with-ai/
I hope that helps. Let me know if you have any more questions.
Thanks! I think there's one other question, then - how do you manage universal vs. page-specific CSS? Page-specific CSS, right? And is it pre-minified in output files? I like to also mess around with preloading and so on. The asynchronous splitting sounds good - as long as there's clarity over how it's done and the ability to tweak it one way or another (even if that means custom functions.)
Q: Will you be running another campaign?

Q: Thrive Architect / Themes
Does Microthemer also plan to support Thrive Architect / Themes as Shallow or Deep integration?

You could tell them Thrive Customers have ask for that ; )
Yep, I've sent them a link to this AppSumo chat. Hopefully I'll hear back soon.

These videos explain how Microthemer optimises CSS as standard and then how to customise things:
- https://themeover.com/automatic-page-speed-optimisation/
- https://themeover.com/load-wordpress-css-on-specific-pages/
- https://themeover.com/folders/
Draft CSS is not minified, published CSS is minified in the output files.
Do these videos cover what you're looking for?
