Sorry but 3.0.1 still seems like it is not ready for prime time. Back to 2.2.1 again unfortunately
I use Toucan for Sync, and so my comments below all relate to the Sync tab.
1 - Mirror option is not detecting changed source files or deleted source files, only new source files.
Add new file to source, it gets copied to Destination
Delete file from source, does NOT get deleted from Destination
Edit file in source, does NOT get updated in Destination
2 - The folder is still not automatically expanded in Source and Destination file lists. You indicated you would fix this.
3 - Opened an old Job created with 2.2.1, it did not fail this time, but when I tried to save it, Toucan froze. When I restart Toucan and try to open it, Toucan freezes again.
5 - Loaded Toucan, set source folder (contains one file) and destination folder (contains no files), selected Mirror, clicked Preview and it took Toucan over 1 minute to do the preview.
Is there a way I can send you screen prints of what I am seeing? They might help explain some of the issues.
