More contrast in the scrollbar, as it's very hard to tell where it's meant to be!
More obvious indication that a page is loading, as it's sometimes hard to tell if it's going to wherever you've clicked, or if you just didn't do it right.
The usual, open new window, open link IN new window, open current FRAME in separate window.
A button *on the toolbar*, or at least *easily accessible* in some way, to flip image loading on and off -- PLEASE!!!!
I do like it A LOT though -- good work
