Un-ticking All Objects under ICM Properties and Themes
The "Properties and Themes" provides the option to Display certain model Object Layers (i.e. Node, Conduit, 2D Zone, etc.). It is a very long list of about 50 layers.
It would be helpful if there is an option to Tick (or Un-Tick) all layers at once.

It is effectively possible to do this already - initially click on the column header for "Display" or "Selectable", then, while holding "Ctrl" on the keyboard, tick or untick any of the boxes in the column, and this will apply the choice to all layers.
Similarly, if you select several layers at once, either by selecting the entire rows for them or just left-click-and-hold to drag a box so that multiple "Display" or "Selectable" cells are highlighted, again, the "Ctrl" + tick/untick will apply to all currently selected cells.
Were you aware of this functionality already, and were asking for dedicated "Display all layers" and "Make all layers selectable" options, to make the process a bit easier? If so, please disregard my comment.
Either way, I think it would be good to have more consistency between dialogue windows - for example, in the "Engineering Validation" window, the above process of "Ctrl" clicking doesn't work, and instead you have to use the "Select/deselect all" tick box.
