I find it very difficult to find my mouse cursor in-game sometimes.
To some it'll sound silly, but I can't imagine I'm alone on this.

Especially when there is a lot of action going on. Even while moving it about, it can be tricky to see.

I play on PS4, where I believe it's worse given the lack of cursor options via the Playstation settings.

Maybe adding options for outer edge strokes or trails, even colour changes to help users having difficulty tracking it.
