Sadly, this extension doesn't work (at least for me) in TB91
Update1: It's odd, I must deactivate and activate manually for the extension work
UPDATE: 1.0.1 version works perfectly
Can you please write an e-mail to k-l-p@gmx.de and tell me what version of TB you use and which operating system you run?
(I use TB 91.0b6 and Windows 10 and the extensions works correctly.)
Update 16.08.2021:
Please update the Add-on to version 2.1.0 - this should work with TB 91.0.
