TickTick is great! - if you haven't tried it yet (via their website or mobile apps), you really should.
I like how this extension pops my TickTick ToDo list into a discrete window.
I can't give 5 stars, as I'm having trouble with using the Add-On to grab a new task/item from a web page I'm on (via right-click). But that might be due to other protection add-on's I'm running.
