This is how a backtrace is currently displayed in the 'Frame Stack' pane. 
While it's an informative display I find it hard to 'decypher' without careful reading.

My suggestion is to parse the GDB output and have a column display as the one in
the 'Watch' pane. Optionally the user should be allowed to change what columns are
displayed and in what order.

This would allow a user to remove information that he/she does not care for. Most of the
time 'function' and 'parameters' are sufficient for my needs. At the very least the user
would be able to make unneeded columns very narrow.
