I have a working AGOL web map that (because layer grouping is not available) has a long list of layers/items in the Content menu. When I need to turn a layer on/off, I find myself scrolling to find it. It would improve my efficiency if I could type in a quick search string at the top. This seems like an easy tool to add. Sorry if this is a duplicate post; I wasn't able to find any other similar ideas.
