i have just uploaded version 0.05; i have included a new feature, which calculates skill volume (tt value of the equiv. ESI chip) and market value of your skills, everything on the fly, at the same time of the scanning process. columns are sortable too, so you can sort your skills per market value descending, and see in the first positions where do you have a higher cash "potential".
i have uploaded a screenshot with some random skill values:
enjoy
