Here's where you can start logging feature requests:

http://github.com/jaysylvester/comitium/issues

You'll need to create a GitHub account. Everything you add should be labeled as a feature request at this point, not a bug, because we're not talking about the current software. Once I open up the software to members for testing, you'll be able to log bug reports there as well.

Incidentally, some of the items you've listed are already a part of the new software and will be available at launch (a mobile layout, for example). The rest have been floating around in the back of my mind in some form or another. The new software will definitely be more modern in its approach. Keep in mind I built this forum in 2007 or 2008 and it's basically been patchwork since then to keep it running. Things have advanced quite a bit in the last 8 years. The new framework will make updates and maintenance a lot easier, and I'm committed to keeping this place running as long as Star Wars fans want to gather here.
