Debugger need step in/out buttons or F7/F8 keys

Currently is very difficult to work with debugger.

Implementation of step in/out buttons or F7/F8 keys would be much more helpful, instead using quite number of breakpoints.

On step in, it will go inside function, on step out will just execute it silently.

Also, it would be helpful that breakpoint can be set/reset only by clicking left mouse on the line number, instead long procedure with popup menu...

Yes, it would be useful, but difficult to implement.
There is plan to do this, but it will take time.

Yes, you are right.

Step Over added at Rev 1133 (experimental).

Only working for AvrGcc and GcBasic.
For other compilers it (should) works like normal step.
