Rated 4 out of 5 stars

Thank you for making this extension. It has been very helpful for keeping my most used pages organized. Almost Excellent.

However, I noticed something when I found I needed to expand the number of rows from 3 to 4 to a group. Rather than keeping the sites in their same group, all the sites moved forward so they were no longer in their group; if there were 9 on the first tab, increasing the number to 4 rows on the first group would move the first row of the second group to the bottom row of the first. It would be really nice if the extension would remember what group certain sites were in so if the row numbers (and I guess column numbers) were increased at a later time, the sites would stay on their original group, rather than being moved forward to fill in the gaps. While not bad if you have one or two groups, when you expand to 10 groups, it takes some time to reorganize the sites to their original groups.

This review is for a previous version of the add-on (0.7.2.5).
