This has been changed since UEFN’s release and since then, scrolling makes it so that icons don’t load, and when you are searching for something, you have to scroll, release cursor, then scroll, release, etc.
It would be insanely faster if we just scrolled until we found what we wanted, like how other map editors do it (eg. Far Cry editor). It’s very sluggish at the moment to try to guess where to stop the scroll, wait for icons to load, then repeat.
The icons in the Fortnite asset database never change, so why not cache them somewhere so we can load them fast every time (forgive my ignorance, I am just comparing with Far Cry editor where everything shows and they have 20k assets)?
