Info on possible validation given chosen charts
Production proof validation using Fogra media wedge or IDEAlliance control strip
Sort table by left-clicking coloumn headers and an absolute sorting option
Custom alert levels in table
Complete re-design of the GUI

2009-12-14 | Destiny of version 0.2

Not a single bug report as been submitted for the 0.2.0 beta1 release, which is both kind of good and bad. I have found some minor bugs to be included in a future 0.2.0 beta2. However, I will anounce the 0.2 branch dead, if version 0.3 reaches beta before 0.2 goes stable.
