Might be too late to request addons for R4, but something that I would like to throw out there that I think others might find of interest as well, would be:
Action SoftKey:

Adds a very nice TF 2.5 Iconset for Quick Actions that are used a lot. I install it on every Flash. I find it great for quick access to Soft-Reset, File Manager, Camera etc.
Organizing Start Menu into Folders like: GPS, Internet, Utilities, Multimedia etc. Not really wanting to copy off other roms, but I do find the organization much easier to get to what I am after than scrolling a few pages etc. I know with 6.5 you can move icons around but sometimes it seems easier to just go straight to the folder that holds stuff like that.
Those 2 things for starters, nothing I can't install myself, just trying to make the ROM look even more professional for stuff all of us seem to use it for.
