maybe not a bug, but inconvenience, I just tried to upload a large video (3gb) then continued to browse, changed profile pic - that stopped the upload without any notice.
also, is posting a bugreport like this, here okay? or do I have to send a mail? doing here would be nice, all in one place ;)
please add a short info to wait with browsing until upload is finished - or much better, upload in background while I can continue to browse.
