Just incase you don't know JM, we all really love this addon and the work you're putting into it!
A couple more suggestions (if not already implemented):
1) SSI Output for filtered forums(like in the original, you can output active topics for specific forums).
2) Ability to output active topics via SSI for more than one specific forum (using above). With the original you had to install one active.CGI for every specifically filtered forum/output.
-------------
Generally I use 1 and 2 above on my site under the original version, they're very useful for integrating specific forum content around the site itself.
If you can do them then that'd mean an end to my pestering =).
