First I love the blueprint system and you did an extraordinary job making it so cool to work with.
As I am generally a C# developer I got accustomed to a few quality of life features like properties.
It would be a great addition if you could implement something similar in Unreal. I know I can write custom getter/setter functions but properties are so much neater.
Aside from that, I would appreciate to be able to add these properties to interfaces. The same applies to event dispatchers.
Lastly a great addition would be, if we could choose actors with interfaces in public interface variables when they are placed in the map.
Right now when you add an interface variable, make it public, place the blueprint in the map and you want to fill its slot with an actor from the map which has the interface applied, no fitting actors are found in the map.
