Would it be possible to enhance the TracLink macro on the wiki to add
another link, besides the current "report bugs" and "request features"
links, called "view tickets". Everytime I go to report a bug or ask
for a feature I find it takes longer to do a custom query on the
correct component to see if there's already a related ticket, than to
actually fill in a new ticket.

So the enhanced macro would output something like:

"Use trac to _report bugs_ or _request features_ (but first, _view
tickets_ to see if your bug or feature request already exists)."

Cheers,
Pat
