Review for Extra Folder Columns by GilbertVK
Rated 4 out of 5 stars
I was very happy with the add-on till I upgraded to TB5. Now weird is, on one laptop MacAir (OS 10.6.8) the add-on version 1.1.3 is "accepted" and seems to be working fine. But on the MacBook Pro (OS 10.6.8 too!) suddenly the same 1.1.3 is said to be incompatible with TB5 and is disabled. This happened after a restart. No clue why. At first I thought there was a bug in TB5 so I did a re-install. Same. How does that work?
So, without any hope I did the following: removed the add-on under Add-ons manager. Went to add-on page and download the same version 1.1.3. Then in Add-ons manager imported. Guess what, it works again. TB does not complain anymore that it is incompatible. Talking about weird!
