Okay. So could you please clarify what you mean by
I thought that's what the config I shared was doing but it appears I misunderstood what you're asking for.I guess to summarize what I'm looking for is something that is basically legacy W/S but camera-based A/D in functionality. Is it possible to achieve that somehow?
I'm at least certain that I did address this part:
Use the Save Current Camera Position and Return Camera to Saved Position keybinds to create a "snap camera to behind character" button.the lack of the ability to press a button and have the camera either face where my character's facing or vice versa makes it a little bit less conventional. The camera is my biggest problem.
The reverse you don't have to do anything special for--it is the defining feature of Legacy movement. Move Forward snaps your character to the direction the camera is facing.
