Comment blocks are great in blueprints, but they can be made even better, if Epics will add some Comment block type, like TODO, FIX, HACK - usual comment marks used in C++ coding. and other user customization comment types, like Collision channels and objects can be setup per project. Default color should be attached for comment type, and some search mechanism for searching comment blocks by type. All these can speed up and make development more comfortable I think.
Those sound like some cool ideas. This may sound weird, but could you make a quick representation of what you would want that to look like? Just a mock-up basically? It would help a lot to explain the request if there is a visual component, since this is going to require aesthetic changes. I wouldn’t want to put in a request and the devs interpret it incorrectly.
