Implemented Sessions like in OWB (different file format though).
Figured out and fixed an annoying crash at the exit after visiting some sites (local storage thread would often crash and burn due to an issue in WTF threading and our pthreads, the latter fixed by Piru).
Improved password autofill.
Implemented mouse cursor support.
Implemented http auth.
If you think those sound easy, mouse support took me two long evenings to figure out - WebCore wasn't using the browser chrome APIs it was exposing to change the mouse pointer and instead relying on some other internal handler for those... Something I hope they'll clean up, eventually.
