* Support OAuth. This really requires OAuth support in python-twitter, but the python-twitter team doesn't have OAuth ready. So I can either cobble together my own python-twitter tree entirely, with the oauth-python-twitter extension + patches, or wait on / work with the python-twitter team on getting oauth-python-twitter integrated.
* "ValueError: list.remove(x): x not in list" when trying to close a tab (error recurred after adding conversation support). Tabs can be reordered, then closed, as a workaround.
