The popups might be a bit slow on a low end/busy/overloaded machine, and sometimes might not even open. Other times when you open them and switch to something, you can't apply changes later due to Cloudflare and have to refresh the page.
Quick options on the game pages would make things easier, for example a button to automatically add alert with the default settings, and a button to remove the alert without visiting the popup. Same could be also useful for the collection button (I use it manually only for family-shared games, and tag them as such).
Not sure about the UI, but it probably could be done on hover of the current button, or as additional quick-themed icons.
