I'm sure others have covered these (they are pretty obvious!), but here's a few:
- Enable variable assignment with declaration, like "Dim Ok as Boolean = False"
- Enable string concatenation using "&=", e.g. s &= " The End", as opposed to s = s & "The End"
- Eliminate the multiple compile popups, a new one with every compile/debug pass; either re-use the single one, or close it when debugging ceases.
- Enable the ability to Copy (and Edit) a variable value, when stopped at a break-point (cf. Visual Studio).
