A few months ago, Hubstore [1] was not compatible with existing Python distribution packages. Today, Pyrustic Manager produces Wheels, Hubstore consumes Wheels and therefore is de facto compatible with many existing applications.
Feedback helps me improve the project. So, I'm glad to read your review !
I just discovered Thonny, I'm going to take a look at it.
Regarding the black color, personally that doesn't make it harder to use [2]. This is a dark theme that I named Cyberpunk Theme. The goal is not to show that black makes a GUI looks beautiful, but to promote the theme/style mechanism I designed to custom the look. I promote a separation between the theme/style and the layout of widgets a bit like HTML/CSS but without creating a another yet DSL. The theme was actually incorporated into the Pyrustic codebase. I removed it weeks ago. Now it is a distribution package available on PyPI. So tomorrow, someone can if they want to do a light theme that they'll call Sunny or Snowflake.
I intend to make a website to show a summary of all the Pyrustic sub-projects, because for the moment you have to read a lot of lines before understanding the project. Also, GUI/aesthetics is only part of the project. For example there is pyrustic.threadom, a library to perform GUI-Toolkit-compatible multithreading easily.
Thanks again for the feedback !
