The author of this add-on didn't stop it's development Rated 5 out of 5 stars

The bug and lags I reported last time are fixed now.
pjs, thanks a lot!

This review is for a previous version of the add-on (2.1). 

Thanks for noticing me, I'll try to correct this in the upcoming version 3.0. The next version will have much faster and easier selection, faster scrolling and more accurate content representation, in addition to quite a few bug fixes.
