Hello, here is my version of the initial UI, that I've started 2 months ago.
Here is my version of the Initial UI, more black, more beautiful, and can fix the issue when you switch the windows, and when you go back to EE, the screen flickers dramatically. It works, someone who had this problem has told me it work, so it could be work also for you. I've do the UI and black, but if I have positive return, maybe more work will be doing.
If you find issue, bug, or other things, please contact me ; I'm proprietary of this work, so if you have idea, or want to change, contact me.
