Hi McNeel
There’s a wish on YouTrack for One Layer On to include the entire sub-tree. Currently the only comment is from Dale Fugier, stating that “Well, this isn’t really “OneLayerOn”…” and he’s absolutely right - it wouldn’t be One Layer On… that’s the whole idea!
Can you please, please add to the right click menu an option to either turn on (only) the selected layer AND its sublayers. As an alternative it could turn on the selected layers, so that you can quickly select a layer and the relevant sublayers (Shift+click) and have only the selected layers on. Right now you have to select the parent layer, right click to activate One Layer On and the select all the sublayers and turn them on.
Yes, I have a Py-script that does this, but I really think it should be in the default Right-click menu.
