Absolutely fantastic, a must-have.

Sync features and a custom page to snooze to dos will make this the ultimate extension, however progress seems kinda slow

This extension makes it easy to check out a page later without having to keep the tab open at all times. No more forgetting or missing things. So far it is the only extension of this kind that has so many options. I hope they'll add an option to let us configure our on menu entries.

no disclaimer on what information this addon collects

Helpful to certain extent. I would like to see, and that would give 5-stars rating, two more features: to be able to make permanent snoozes (a site that will show every morning at 7, the other that will show every Wed and Fri at 11 etc) and to be able to set my own default time (let's say 7 instead of 9).
Also, it would be helpful if we could see all the snoozed tabs, and unsnooze one if we want.
