I would add, and I've "wished" for this in the past, that the editor be allowed to open/edit text files. When I develop on a laptop, I can only fit B4A on the screen. When I write notes, documentation, etc., I need to open a text editor someplace to do it. It would be nice to edit these within the B4A IDE. I would think a simple way to keep these non-project files out of the build is to only compile and build *.b4a and *.bas files.
I can do this in Visual Studio and MPLAB (PIC microprocessor IDE).
