Agreed. Definitely a must-have! Rated 5 out of 5 stars
Nice and clean implementation. Nice features and works really straightforward.
Just because I intend to use it as a must-have, I would like to make some humble suggestions to make it even better.
(1) Shortcut -- Click on that small icon in panic is challenging.
(2) Some user like me already hide their bookmark toolbar. It collapses to an icon (I can't provide screenshots on AMO but you can try this using menu "View-Toolbar" and uncheck "bookmark toolbar" to find the collapsed bookmark icon appearing. The *problem* is: when you toggle "Presentation Mode" and toggle back, the bookmark toolbar reappears.
(3) Pinned tabs. They are unpinned when you exit Presentation Mode.
(4) The active tab before entering Presentation Mode should be restored. Now when I exit Presentation Mode, the first tab is always active.
Thank you so much to bring us the long needed feature. Keep going in the right(er) direction than Mozilla's less useful "New private window" mishmash.
Thanks for the feedback! Many other users have requested these features and I plan to address them in the next release (which should be soon).
