I really wish people would stop trying to innovate with user interfaces. In a comment below you criticize this UI because it doesn't have delimited interface elements. I agree that non-delimited user interface is really bad, but I attribute that mostly to Microsoft's flat design innovation, which I didn't like at the time, and I still wish I hadn't had so much influence.

As for invisible scroll bars, again we agree. But I think that was Apple. I'm sure somebody will correct me if it wasn't.

That "Android-like" is based on LVGL which is a brilliant GUI framework for ESP32 (not invented for this project) when you consider the low capacities of the hardware and how efficiently it pulls the animations.

If Android had such GUI, it would be a heck lot faster and drink less energy.

MIT lisenced; feel free to fork it if your feeling especially filial

What would you have wanted to see?

At the first look: clear delimitation of UI elements, usable scrollbars.

I mean I kind of get your frustration, but I don't think innovating the user interface is not really the goal of this project, the opposite actually, it's moreso trying to provide a well-known user interface to devices where that was previously hard, so the goal is to be similar.

I would like to see some fresh ideas in UI though, everything is the same nowadays... :(

It's FOSS, so you can use it primarily for output with real switches and knobs for input. But then just using plain LVGL would probably be more practical.
