Hi! This is Mooquackwooftweetmeow, a collection of stuff by Greg K Nicholson.
I have one fairly major complaint about Gmail's web interface - you can't open multiple emails in tabs by middle-clicking. (Pot+kettle sidenote: one can't middle-click links in this weblog either, but that's an XSLT fault in Gecko.) In fact, it seems the links one clicks to open emails aren't really links at all (right-clicking offers no Open Link in New Tab/Window options). This would put me right off using Gmail permanently.
Qute, Firefox's old default theme (and Thunderbird's soon-to-be-retired default theme) doesn't have borders on its toolbars (at least in the latest Firefox version; see also the Qute FAQ). Winstripe, the new default theme, does. Personally, I prefer no-borders - it looks cleaner.
