Layer Grouping for Show and Hide
You should allow "groups" of layers within a Project to facilitate easy hide/show.

I just wanted to bump this as I share the same desire. I would also like to add that multi-tier grouping would be ideal.
For instance, in regards to grouping Tracks:
-Operational Period 1
-Operational Period 2
With of course the same request for other layers. Show/Hide is the most desired option, but of course multi-edit in general would also be a great feature.
The second y'all push a multi-edit update (with these groupings/folders), this software makes any other SAR mapping alternative obsolete.
One tip would be to create an Overlay for a group of layers that are not often modified. Create a set of routes (or markers, or tracks) and Export them as a ShapeFile or KML file. Then import them back in (into the same, or different Project) as an Overlay. Then use the Edit Overlays window (Layers menu) to control their display, etc. Overlays can also be shown/hidden via View, Layer Size/Visibility.
