simple useful- worth trying it out. Rated 4 out of 5 stars

updated review after developer added a better description and instructions (thank you). extension works pretty well and can potentially make organizing of emails better when using sub-folders. it essentially rolls-up emails in certain folders. would love to see it rollup non-smart folders. not sure if it's an essential add-on yet. will keep using it.

This review is for a previous version of the add-on (1.1.1).
