There were a couple of not so important things that had drawn my attention in the past. Considering a new release is on its way, I thought they should be mentioned. I'll try to remember them all in the meantime. Here are a few.
1- There is a typo in 'settings->environment->colours'. Item 'Editor:Highlight occurrence' is written as 'Editor:Highlihgt occurrence'.
2- In 'settings->editor->syntax highlighting', the chosen color for 'active line' isn't reflected in the sample code below.
3- The installer for 13.12RC1 displays '12.11' while loading but I'm sure that will change in the final release.
