This plugin is such a steal compared to many others on the market, given all the modules it provides. It easily trumps the list of features other plugins offer. The functionalities that were essential for me included the folder functionality. As I have hundreds of pages, organizing them became much easier. The ability to customize the login page primarily for clients made a good impression. The visitor actions tracker, as I mostly outsource work to developers, allowed me to check what they have been doing. Website resources and settings are all visible, and it also allows for applying JavaScript and CSS into the dashboard, which many other tools only do for the frontend. This was quite essential for me as I had several plugins whose licenses were either plainly visible or could be shown through element inspection. There were also quite a lot of other modules on offer.

I did notice several issues and hope this feedback can help the developer make the product better.

It would be nice to disable the UI of Adminify to override the plugin's UI but keep it enabled for side menus and the admin panel top, like ways to disable the UI when editing pages/posts. The UI of many plugins gets messed up, like grid builder toggle and settings, bricks builder settings page, AliDropship, etc.
When configuring all the settings, I had a hard time exporting and importing the settings. The backup seems to be dysfunctional. It would be nice to have this properly working as it takes quite some time to reconfigure Adminify for every website.
Not all of Adminify's UI elements' colors were customizable; some of the text colors didn't match the customized website.
The current UI themes seem to be too colorful in terms of contrast, not something one would like to deliver to a client, but perhaps others might think otherwise. It would be nice to have more options like grey, light blue. Currently, I have to customize.
Some improvements I can think of:

A security module would be nice.
Implementing captcha when customizing the login page.
More details in actions of users, including IP address, payload/value.
Overall, this plugin is really wonderful and brings lots of value. The benefits outweigh the cost a lot, hence 5 tacos.
