Outliner custom filters - save scripted expressions in the search field

I find the filtering possibilities for Outliner very limited when dealing with complex scenes. Filtering by object types should be a standard for example. (In 2.92 there are meshes and emptyes available)

But I'd like to propose a way to define custom filters.

Say you need to find and select/show only meshes without UVs or with second UV channel or lighs that are off or not casting shadows. For this you need to google/write and run a few lines of code in text editor.

This can be simplified by the possibility of saving small scripts like this in a list, with custom labels. A good placement would be the top search field with a dropdown list and a few buttons for management. The search box shoud be also the input method before saving them.
