Rated 4 out of 5 stars

Tested it in a scenario with two scheduled actions while the browser was open, and it worked well. Still, as others commented, the UI needs work. For instance, Options opens up the scheduler itself, when one would expect actual options (like not showing the item menu in Tools, and so on). It has great potential, especially if the scheduling rules become more advanced.

Good work.
