Could you add the option to auto add to the one tab list tabs that have not been visited in for example a week? (With the amount of time being configurable up to a month or something like that)

Could you also add the ability to manually create new tab groups and be able to contract and expand the listed tabs on the groups?

This is easily in my top 5 WebExtensions and one I cannot function without but be warned!! Back up your OneTab by importing them at least daily as it is is very flaky and you can easily lose your 500 tabs as I have done on more than a few ocassions. DO NOT USE CCCleaner to clean your hard drive as it will also wipe out all your tabs. I have written to the developers on 3 instances to try to overcome these issues but you will never get a reply which is why I wont rate it with a 5 which it could so easily be. It is the best Tab saver type extension available except for the flaky nature and no support.

There is a bug in this add-on which I thought would be resolved by now. I am on Firefox Quantum and 'Restore all tabs' does not work. It just loses it. I have spent countless hours going through my history to visit the pages again. Restore all fails every single time. Luckily, I found a way to stop this. I lock the tabs nowadays and share it as a webpage to use them. Very inconvenient. Please look into this issue

i just suddenly lost all my saved books from this shitty extension.do not touch

I'd really like it if clicking the button just added that tab to a one-tab list instead of adding all my unpinned tabs at once, or if I could choose this behaviour in the options menu.

The system of collecting all tabs I'm not currently using in a single tab is promising, hence four stars, but the current implementation where I send all tabs at once to OneTab isn't super useful to me.

Nice design and enhencement of tab groups.

Thanks for update for FF Quantum =D
