I forgot to thank you for your very detailed tutorials and documentation. I am new to SU and appreciate your work very much.

Thank you for your reply which prompted me to look closer. I am embarrassed to tell you that after clicking the "Detail" button I got this.

Is LOTT compatible with Mac OSX Mojave (10.14.6)? I have installed it several times using SU extension manager and sketchUcation plugin manager. After restarting SU a message says that LOTT was not installed although both managers indicated that it was installed and enabled but it didn't show up in any of SU menu's.
