Currently the summary text of breakpoints are
almost useless.
Regarding the thin space the table has in the
default vertical layout the most important
information like the line number and the class can
only be seen when the scrollbar is moved. With a
single reordering of this textural data the
usability can be improved.
I think something like this:
<line>:<classname>, <package> for java classes
<line>:<filename>, <path>  for JSPs or whatever
else we have.

I have an other thought of this breakpoint
display, as a UI designer, but I will fill it as a
different issue, as I would like to see this issue
implemented as soon as possible. (I think the
solution is trivial.)
