Wow. Thanks for the feature. Now browsing the long complicated "tables" in Details (with dates, tags, labels and comments) is even more comfortable. After enabling "Highlight hovered icons" once I will never come back
Though I have to mention (and then remain silent) that the feature works perfectly in Details view of List area.
The hover square is drawn almost immediately.
But when switching to List view of List area, it is a little slow. The hover line is behind the cursor. Thumbs view is even slower.
If I compare XYplorer's highlighting to Explorer's behavior:
XYplorer's Details view is smooth and fast, I would say even faster than Windows Explorer (Windows 10). Definitely faster.
But highlighting in XYplorer's List and Thumbs view of list area works two times slower, and is a little distracting.
Maybe some tweak (to limit this feature to the Details view) would be nice.
Tree also works well (but the Catalog and Details View of list area are faster).
