How to create custom class with custom inspector ( detail view) (executing buttons etc.)?
I’m starting with this Engine. 
Make a blueprint which includes custom events which run in the editor. Select the custom event node, in the details panel is the option ‘run in editor’, this will make a clickable button in the details panel in the main editor window…
It is quite difficult to clarify my question because i don’t know how this is exactly named.
I’d like create something like [Modes] panel for my classes.
Ah, obviously once you have placed any of your actors, they will be in the ‘recently placed’ section.
But if you want to make your own modes panel, then I think you need to write a plugin.
Any tips? Have u ever heard or saw like some similar?
