tabs are the wave of the future...err, the present!
It would be awesome! yeah
for Feynman's sake...
This is the biggest if not the only issue that I have with Orweb. I think it major usability issue, for example if you are searching for information about something and always have to press back button to return to search engine results (and naturally press back too much and lose your results).
Orweb is probably the only web browser that I have encountered lately that doesn't support tabs.
Especially given how slow browsing can sometimes be. Tabs are a direct workaround for all-too-common "did I actually press 'back'? did I mean to press it another time?" errors which are then even more costly and frustrating when the link is slow.
