I think it would be pretty neat if there was a marker on the world map of where you were at (friendly to players who are new to rscrevolution and haven't recognized the map).
Another thing that might be nice to add in my opinion would be to be able to click on a certain location (I.E the fishing spot in taverly) and a marker would be placed on the map and a small red arrow would appear on the screen to show you where to go to get to your destanation.
