I put together a spreadsheet to manage my magus's lab time. Now I want to make it more general, so I revised it a bit. If anyone has any suggestions on how to improve it, or has a better one he wants to share, please do tell.
The spreadsheet is arranged so that I add XP in Abilities or Arts, note raw vis income and expense, and so on. The sheet determines the ability and art scores and so on from these fluxes. It does NOT present the information in the form of a character sheet - the idea is to use the spreadsheet to manage my lab time and raw vis, not as a replacement character sheet.
Although that's a future improvement, I guess, if I could ever figure out how to do that.

The spreadsheet is in OpenDocument format. If you want to open it and don't have OpenOffice, download OpenOffice - it's free, not excessively large (~100 MB), and excellent.
