It would be extremely useful if there was a "hide in all views" type tool. Especially on larger projects with many views. if there is something I want to hide(or even temporary hide), it would make the process much more efficient. One could simply "select all" the item they chose, then "hide in all views". A process that could normally take a lot of time, reduced to two simple steps.
This could apply to detail groups, 2d elements, specific line/text types (used for internal markup of drawings), etc.
