Blackdrazon: Here's a feature request, if you could: we can hide the Alerts icon, but the number still adds itself to the tab's Title bar. For example, right now I'm seeing the title: "[1] Barefoot Essentials 2 - GOG.com enhancement, page 95 - Forum". It'd be nice to turn that [1] off, too.
DawEdhel: I think, the better approach in this case would be to auto remove any notifications silently in the background, as you are still going to accumulate these alerts over time needlessly.
I also wonder, if either alerts have any expiration timer intervals or they have to be removed only manually.
That's good thinking, I like it! I'm pretty sure wishlist alerts disappear after the sale they're attached to is over, but I don't know about the rest.
