I wish someone would write a new map UI mod for LOTRO

I wish someone would write a grid overlay type map mod for LOTRO. I farm by crossing the map [hopefully] evenly so I can catch the ore or wood spawns [and sometimes critters for hides] but it can get annoying getting off course. In World of Warcraft you could get a little firefly trail to follow, I would love something like that to ‘lead’ me along a set course [I figure it would be something like open the zone map, hit ‘F’ to mark a spot the firefly would head to, then when you reached the end of your ox-row, you set a new plot point.] I hate being sucktastic at coding, or whatever you call making UI mods. sigh
