This feature will fundamentally change UEFN build creation and add back the missing link of not being able to move between islands.
Having the ability to set another level as an actor palette then drag and drop content to your map will speed up workflow many times over.
Inagine the residential furniture template used with this feature, you ll be able to make interior 4 times faster (maybe more) than Creative, which atm 3 times faster than UEFN. The speed will be insane. We need this bad
The way I would imagine it working is that you make a new level, place your galleries in it or load your template, or stored template, or mechanics, then you can drag and drop actors to your map. You could also multiselect devices and they will self link the events on transfer so everything is plug and play. So mich potential!
