list of file types and the like by blocks

[CompSystems]

Hello,
One feature that would make viewing files easier is that when the files pane is organized by a certain item, for example extensions, put a blank line to separate the extension lists. in this way, a complete list is not shown but by set of elements.

Now having this separation of elements, to facilitate going to a certain group of them, allowing to compress or expand these lists, this could be done next to the numbering column, adding a button [±]
