No me oculto las pestañas que tenia, me borró todas y no pude recuperarlas. No funciona con muchas pestañas

The new version version completely destroys the old windows and tabs. I lose all state. It is not a quick change anymore either, my computer isn't the fastest. It is very noticeably slow and opening and loading the new window. The closing is slow but the new window shows first covering it. So I can live.

Used to love this addon, but last week there was an update or something that totally changed it for the worse.

1) Used to be able to change the hotkey (I used F1) but it's now locked to F9.
2) "Hide Windows" used to minimize the window into a small icon, roughly the size of a desktop icon. This is no longer an option.
3) It straight up doesn't work. After using the "Hide and Replace" option makes the hidden page, I can't reopen the hidden page(s). I've tried pressing F9, clicking the 'Panic Button' icon, nothing works.

I might be wrong, and just not using it right, but I like to think of myself as relatively tech savvy.
