The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but it's a work in progress, and many features are still pending. Some minor hints on how to use it:
Folders are used as project (and .gitignore is used to ignore files)
The wheel icon on the top-right has all the options you need (Ctrl/Cmd + M to show).
Some keybidings to navigate any project (navigation is keyboard driven):
Ctrl/Cmd + K = Locate Files
Ctrl/Cmd + Shift + F = Global Search
Ctrl/Cmd + Number (Go to tab #)
