I like the latest update; there are still a few things I would love to see in the next update. For example, I can only see 4 of them after grouping icons unless I press the tile to open the group. There is a way to force it to show at least six icons, but I would love to see all of them... without that, I feel this feature won't work for my needs unless I force myself to create groups of 6 icons each or don't use the groups at all. That being said, while I was writing this post and going back and forward to make sure I was describing my problem correctly, I noticed there's a feature to add Fences... that is a workaround since I can see all the files/icons I have in each fence acting as a group. The right-clicking is slow, but I guess that will improve over time.
I would be very happy to see a feature to add a custom image or custom icons for groups (no need to show multiple icons, I just want 1 icon to represent each of my groups since I'm faster at reading and relating symbols to categories).
Please keep it up the great work, guys
