Rated 5 out of 5 stars

This add-on is an absolute must for me, I realize this now that it no longer works with TB 78. Thank you very much for the coming update, I'm patiently waiting for it!

This review is for a previous version of the add-on (4.18.1). 

No worries - if you want a test drive there is a prerelease here already:
