1. Actually tabs are very useful (that's why we have them in most of web browsers ). For instance, you are on a forum and you have to do some tests on the website. You need 2 tabs to switch between the website and the forum.
Tabs are also handy when opening several websites from a RSS feed.
See OP. I don't have the possibilities.
No not planned (same reason as point 1).
6. I would say 3 modes is perfect lol:
- hide statusbar only
- hide statusbar and navbar
- fullscreen: no statusbar, no navbar, no omnibox
Implemented in next version (I'm testing one/two days before release.
See point 1. Perhaps later... seems possible for me...
BTW: I added license on github.
