Bit confusing Rated 3 out of 5 stars

I get that it is supposed to free up memory occupied by a closed tab, but the specific options seem ambiguous. Help file tells how to use shortkeys but doesn't show what each function really does. Garbage collection vs Cycle collection, for instance. Memory minimization is meaningless as it could mean different things.

This review is for a previous version of the add-on (0.9.1-signed.1-signed).
