Something that I noticed that Brave lacked across all platforms (at least IOS and Mac that I use) is the ability to have tabs close automatically if they haven’t been viewed in a set period of time. This is something that iOS Safari has already. I think that, especially for mobile, it could save battery power and reduce the hassle of having to manually close tabs, as well as potentially speed up the launch time for the app. Especially on mobile I find I tend to open tabs and then leave them, never opening them again (until I realize I have way too many open and go to clear them)
It would also be helpful to have a clear all button in the mobile app.
This would be a helpful feature and I hope to see it implemented!
