Chris,
Just have to give credit where it's due.
5.51 / 5.52 have been excellent upgrades and really helped to solidify WM's position as must-have app for MacOS.
Having supported the app from the very start, with its ups and downs, and continued development cycle, it's a credit to you for sticking with it and taking it to a level which is equivalent now to the speed of the late, great Unsanity's WindowShade X, and even the original Apple built-in version.
Thank you!
