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.

If you don't know what this extension is for why did you install it?

And your rating is based on things you don't know about?

Added more description.
