Rated 4 out of 5 stars

I really love this addon and I want to support the developer but I hate subscription based software.
Please set a price for a lifetime subscription or once off payment

This review is for a previous version of the add-on (5.5.2). 

I will consider it, but in my experience I have to work a number of weeks on the Add-on every year to maintain and make it compatible with the ESR changes; if I hand out a permanent license to all my users I cannot guarantee to work on compatibility for free forever - of course it's also a matter of getting the price right. In the meantime there is now a Standard license which is around 5 bucks.

I highly recommend to add this suggestion to the issue tracker and then we can discuss it seriously - https://github.com/RealRaven2000/QuickFolders/issues
