Hi Thomas,

Yes, debugger is still in development, please let the dev have
backtraces of any crashes, thats the fastest way of getting them fixed
:)

Yes, with all due respect to its developer, I think debugger will
never incorporate all the gdb capabilities into the gui.  And I don't
think he is trying to achieve that.

Sure, just pointed you at the plugin because if it met your
requirement it would save you much work.  (And I might have persuaded
you to help on it :)

Probably best to just make a pull request (preferred) or a patch and
lets see.  Don't forget to update the manual to include your new cl
option.
