Good, but not polished Rated 2 out of 5 stars

When I right-click a tab and set it as "important" it is not set as important, but rather the selected is the one that is set as important.Can you please change that behavior to the more natural one of setting the importance of the actual tab being right-clicked?

Great, but needs features Rated 4 out of 5 stars

+1 for the review about the custom color highlight. The comparison with FlagTab is correct and colorizing tab text is a good start. But blue text isn't enough. Adding a context menu with colors to choose from is a kick-off start.

A more advanced feature then would be to have a way to have a list with the important tabs in order to quickly to them switch.

Excellent addon! Now when Flag Tab is dead it is only addon with similar purpose Rated 5 out of 5 stars

Please add highlight (with custom or pre installed colours) feature. It will be great improvement. With the time this addon will be very popular.
My best wishes!

I predict millions of downloads for this addon Rated 5 out of 5 stars

This addon has only 29 users up until now (December 19) which is incredible. Maybe you don't know about important tabs and non-important tabs. Important tabs are the weekly schedule, 'faces' of new colleagues, quarterly results, the canteen time table. Non-important tabs are porn.
With the addon 'Important Tabs' you can close your non-important tabs with one mouse-click. Highly recommended!
