I'm not finding the distance markers especially helpful and might just turn them off to save on memory.
Some things much higher on the priority list would be nice rather than this and new pants, there are piles of them to mention, some even on the road map like
- Shot-shaping and stance controls
- Up/Down/Side hill lies
These are critcial to the game play and a big adjustment for everyone, more so than new pants!
Also from the player suggestion list, a putting green and driving range to try out new clubs would be especially helpful (more so than the distance markers IMO), saving replays in multiplayer modes, reputation tracking, timer options, just to name a few more.
