Hopefully, yeah. I think it's high time we tried to figure out what we need 
from the markinterface from KDevelop.

I remember fighting with it when I wrote the bookmarks plugin, and I think 
pretty much all problems comes down to: a marker has no user accessible 

It would be very nice to have signals for markerRemoved(type), 
markerAdded(type) and markerMoved() instead of just the simple "something 
changed"-signal of today, but that information could be assembled on the user 
side, if only the markers had identity.

Yeah, that's what I meant. :)  Leave the editors markers alone, and recreate 
the corresponding breakpoints on the next debugger run.

I guess we'd also need to remember which editors have been typed into and 
disallow creating new breakpoints for them during the present debugger run.
