Thanks for the feedback, I appreciate it. I have tried Rogue Cats tracker of course, and wasn't happy with it so I made my own. Wouldn't have done that if it fulfilled my needs.

The process is quite simple for crystiter:
1. Wait for someone to pick up an assay bot
2. Move the mouse to the land they're assaying
3. When the assay result is shown, click on the land and select crystite level. (Works even if the map is not displayed)
And if you need to focus back on the game screen without tracking, click on the status bar.
I'm not saying this one is better or worse, it's an alternative to manual tracking that's all. To avoid typing there could be another window that pops up when you click on the land, so you click instead of typing. But if everyone prefers Rogue Cats version instead, I don't see much reason to make an update...!
