Many B4A users are probably coming from a background of Visual Basic 6 or Visual Basic .NET, so this would help.
Example
(1) F5 to compile and run the app
(2) F11 to step through the program one line at a time
(3) F9 to add a breakpoint at the current line
Would be nice, but would probably take much, much work on the development team's part:
* While debugging, allow the user to select a block of text
e.g. (tankVolume(i+1) / maxTankVolume)
and evaluate the value of the expression at that time.
Thanks for a great tool
