It's a long time since I dived into an AppSumo product and had a grin from ear to ear within a few minutes. Most of the reviews I've read I agree with.
As a user, I'm someone who wants a visual way of communicating process workflows, including at least some of the branching and filtering going on inside automation systems - or for instance where they exchange or update other data sources. Here's my two penniesworth:

Pros:
- Really clear structure in the form of Workflows, Teams, People and Tools. I didn't need to watch any onboarding material, it all felt very logical to me and a bit of experimentation revealed the less obvious stuff like how to use Roles.
- That said, you can see there is plenty of onboarding guidance built in.
- Very quick process diagramming is possible, and it's very easy to read the results.
- It's structures may feel limiting but they keep you on the right path - when you're in Visio or Miro it's so easy to start mixing the information you add to each panel and so on.
- So many useful little shortcuts likle the color-coding you can choose for your common tools

The drawback:
- It's so compelling that you just want it to be more feature-laden. I found myself wishing I could add more information to the Step cards visible in the main window; to import automation workflows from tools other than Make and so on. The more you use it, the more it feels like it's missing things, because the basic product is THAT GOOD that it feels like it should have more. I want more!

Some little wishes:
- resizable cards. I get that it starts being more like a generic drawing package then, but perhaps to keep the lovely style consistency you could toggle "bigger" versions of cards with images and links more easily accessible in situ. I found myself wanting to drop in screenhot thumbnails. At the very least, the facility for the Step titles on the cards to be hyperlinks, and to have a wee subheading or details field in a smaller size.
- Placing graphics on the background (especially resizeable SVGs or the like)
- An easier way to chamge the nodes the connecting lines connect to (or I may just need to watch a video)

Really great work - it's been cooking a while, and I'm interested to see how it progresses. V happy I went for Tier 3.
