I just tried 5.22, and although it is a big step forward, the 'Synchronization checklist' misses some expected and useful options:
- change sync direction
- delete file
I regularly need these, and as they are not found here I have to exit the checklist, clean up the mess, start the sync again, repaet the whole thing as I forgot one or two files...until finally I can run the 'normal' sync process.
Adding these two options by a right mouse click on a file and by two more buttons to the right shouldn't be a big problem, and will have the checklist (the sync function) on par with other sync tools (that OF COURSE always have such options available).
