This is a lifesaver, I do most of my logs via this extension, using the "Start Timer" in my GMail.
Only a couple of things need to improve for this to get 5 stars, and that is the project tracking and popup showing.

The extension needs to remember the project for each URL consistently, now it mostly doesn't work. Most of the time I just get a blank project when I "Start Timer", even though I have "Remember project per URL" selected, and a default project selected. (And GMail changes the URL when you view an different email)
Also I want an option "Use previously selected Project when starting timer".

Above wouldn't be much of a problem if the popup that sometimes pops up after clicking "Start Timer" appears always consistently. Now it happens in maybe 1/10 cases, no idea why. If it appeared always above issue wouldn't be a problem. I do have "Show post-start popup" selected.

Other than that, just want to say thank you, this extension is a great help :)
