It would be great if Revit offered more control over selection highlighting, especially for complex items. Part of our workflow involves referencing 3D store layouts as a linked (essentially AutoCAD solid model) linked file. This is to avoid creating hundreds of old fitting families for items that will be phased out with relay plans. Hit one of these, or a linked Revit site for instance, and the highlight can become annoying.
The screenshot below shows AutoCAD’s ability to exclude Xrefs, Hatch and locked items from the onscreen highlight. The equivalent options in Revit for linked files, patterns & pinned objects would save quite a bit of screen freeze time.
