in many IDE's I have seen a button which is like a yellow arrow, which always takes you to the current execution line.
BEcause this is an action that one needs rather often.
I have found this much user friendlier then the 3 step solution we have now, which is slow, since the popping up of the callstack is not that fast.
I would suggest we add a similar thing ? And if we would not want to waste a button on it in the debug toolbar, we could give a menu entry in the debug menu we a key shortcut on it.
What do you think ?
