just sharing a quick thought:
Synchronize Panel. FIRST we define the folder for the Sync-Source, THEN we define the folder for the Sync-Destination, CONSEQUENTLY, due to this LOGICAL ORDER, the Sync-Source field is ABOVE the Sync-Destination field: all this makes sense and feels natural.
Well. After hitting the "Compare"-button i would expect the Lister for the Sync-Source to be on the LEFT hand side (and the Lister for the Sync-Destination-field to be on the RIGHT side). Why? this would feel natural and logical, as writing/reading a text from Left to Right feels natural.
Typically, "synchronizing" means we update the Sync-Destination by copying NEW files from the Sync-Source to the Sync-Destination. Copying (similar to reading, writing, following a time line in a media player, etc.) feels most natural when it goes/runs/flows/rolls/swims/follows FROM LEFT to right. Clearly, after hitting the Compare-button the Lister for the Sync-Destination should imho appear on the RIGHT side (of the dual lister in checkbox mode).
The current implementation (Dopus 10 latest beta) is vice versa. Anyone who agrees/disagrees with my point of view?
