Jorge,
I have no immediate plans to change anything actually. I'm working on a new app that can show on the map GPS tracks that have been stored as GPX. And recently I've been so busy with work and family that I haven't made much progress with it.
I thought that the current location arrow is not that distracting or blocking the map that much. Can you send me a screenshot of a situation where it bothers you?
I have occasionally played with a thought of allowing users to select their own preferred location icon from the device storage, but it has been very low priority so far so I haven't implemented anything.
