Devs, this is important in terms of privacy and security.
I just found out an extension I use sells all my browsing activity (it's Rakuten, a cashback extension.) I still want to use the extension, but from now on will need to enable it only when it's necessary.
I also want to use other extensions that request "All data from all sites" permission, but only selectively enable it.
Just add a right click option to disable the extension, without removing it from the toolbar. I don't know the architecture of how you guys do it. Having a separate "disabled state but still show in toolbar" might be more of a project than it lets on.
Hell, I think it would make more sense for disabled extensions to still show in the toolbar by default, rather than the current practice of removing them. Otherwise, there's not much of a different between disabling and deleting.
