Rated 3 out of 5 stars
Kudos for the great idea. However I'd like one of the following improvements made to the addon.
1. The clock gets shown in one of the tiles on the newtab page(like Opera)
2. (Alternatively) The clock should be resizable and coexist with the Tiles on the about:newtab page. Or, maybe a thin digital clock can be placed above the tiles.
3. (If 1 and 2 are undoable) Make the addon restartless. So, that I can start/stop it when I need to focus, and when I need my tiles on the newtab page.
With your talent, you could also consider making a new addon with feature 1 or 2 above.
