The official webpage is still a work in progress, but filewrangler 2 is now available for your enjoyment. Requires 10.5 and higher, so I’m leaving the original v1.2.1 up for those still on earlier systems.
Version 2.0.0 is available here.
The manual is available here.
(Version 1.2.1 is available here.)
I hope the new software is to your liking!
