Rated 4 out of 5 stars

Great add-on.

I setup mine with 18 thumbnails and it takes FOREVER to refresh them all if I change a thumbnail option (e.g. PNG to JPEG).

Is there anyway to speed that up considerably in the next version. By the way, that will be when?

This review is for a previous version of the add-on (0.7.0.8). 

The problem with that option is that it requires all the thumbnails to be refreshed, but you can just open Speed Dial, right click and choose "Refresh all"...
