New features? How about fixing in V4 the major bugs in V3? (Apologies for adding my comments to yours Hybrid79)
I find the new version, whilst more restrictive in licencing is not a problem, does not address any problems I experience in V3. I know Fences does not like multi monitors and if used on a laptop it's not a problem. But in my opinion Object desktop its more suited to a PC and nowadays a lot of users have more than one. Also we tend to turn the screen off but leave the pc running/asleep.
Coming back to a pc running V4, I see no real advantages. Its still buggy, I have to relocate and resize folders on the primary monitor. Using a saved snapshot does not work.
Moving a portal folder does not move other icons out of the way so I lose shortcuts.
So yes there a few changes, mainly for licencingit seems but no real incentive to upgrade as far as I can see. Please prove me wrong.
