Recap Project Navigator does not allow you to select a range of scans and then turn them on or off.
This problem has been reported before and the idea status was changed to "implemented".
I am posting this again because the problem has been solved only partially.
You can isolate a scan by alt-click and turn all other scans on/off by one click.
The alt-click solution solves only part of the problem and it has a bug.
It works fine if you only view one scan at a time and revert to all scans visible by alt-clicking the scan again.
But if you isolate one scan by alt-click, then open one or two more scans by clicking them, you can no longer make all scans visible by alt-clicking again. The only way to get all scans visible again is to click them open one by one.
This can be very frustrating if you have dozens of scans.
There is also the possibility to create groups of scans and turn the group on or off. However, this is only meaningful if there is some permanent use for the group. Dragging scans one by one to the group just for the purpose of viewing them once does not make sense.
Why not implement the standard multiple select (shift-click and control-click) selection methods that are used almost universally in desktop software? Select a range of items from the list, or pick a set of individual items, then turn them on or off by a single click.
