Lot more to come, I spent most of last weekend working on the actual design of the theme; see attached for a sneak preview (hope you all like it!!)
Most of the work has been done on the Email section only though, I want to make some bigger structural changes to the other pages (too much wasted space on the right, thinking of bringing the folder list into all of those pages so the user can navigate back to the email page for the folder they want to view)
It's not even IE7 compatible yet though, and I haven't even blended the .gif's with the new background colour, so it'll be a while before the next update, a week or two at least. I've done enough for now anyway, just need to get it looking better and add a few features then I'll post the update.
Edit: I'll be making it "language proof" and adding text labels too, so if any one finds that there are problems with foreign languages not fitting and they can't shorten the wording any further then it'd be good to know where I may have problems before I do any major changes. eg. if there is a commonly used word that is short in English but is long in a foreign language, let me know!!!
