It doesn't interact with the client in any way, it's pretty much just an upgraded version of notepad (which I use for lots of UO things) so I can remember what nodes give what and what rune I need to click next. I spent many hours mining out every cave in fel to find nodes that gave a good amount of ore, and also a good percentage of colored ore to iron. The numbers on the left represent the runes in the books, for example 1/23 is an average of 1 iron to 23 colored ore. I just did two run throughs (the first to find the nodes then the second to double check them, then I averaged the results), then I arranged the runes in order. Anyways, the tracker is pretty much just a bunch of mutually exclusive radio buttons, you select what the node you are on is giving you and that way you can run back through the nodes for anything that you specifically need. The column of radio buttons on the right is to keep track of which rune you are currently on (1 L refers to the first page of the runebook, the left side). I need to add a save feature, which I haven't figured out yet, but I'm pretty happy with it so far. I made it with microsoft visual basic express edition, which I DL'd for free, if anyone else wants to make their own database/tracking type utilities.
