UX Improvement: Search function in layout editor

Unknown

Hello, 

I would like to share this very simple idea that - I think - could improve a lot the UX, in particular for the developer.

In the layout editor, there is the possibility to search among cubes, entities and more. This is extremely useful.
But it would be even more useful if it wouldn't refresh everytime one drag&drop one of the results of his search.

One often has to use a bunch of cubes with the same prefix (for instance, REP, or CLC, or whatever) and it really makes no sense to search for the first cube, refresh, search for the second cube and so on.

Thanks in advance,
Federico
