Proposal
Change the color of nodes that send to a custom event to differentiate them from functions that contain user defined logic. Not a custom, or user definable color. Just a hard set color.
The Problem
Currently function nodes that contain user defined logic can be indistinguishable from functions that send to custom events and contain no user defined logic. They can differ by name only. This paradigm allows for the following to happen. A mistake easily made by people new to Blueprints, or with bad/no organisation habits.
Purpose
Better visualization that is needed when inheriting, or trouble shooting a project started by someone else by providing clear and distinguishable feedback to the user.
Closing
Currently this can only be alleviated by over using comment boxes, and/or being diligent with naming conventions. Comments are a problem because when they are nested they become hard, and in some cases, impossible to manage. Good naming conventions, while simple, are not always practiced. This change would alleviate both requirements while also providing better, instantly recognizable, visual feedback to the end user.
