Just few small things:
- program still displays version 0.6 instead 0.7
- clicking OK in preview window doesn't seem to do anything
- I don't quite understand the preview window since it seems to display my original pdf
and one new thing - I was just wondering if it wouldn't be useful to add label / textbox with a cmd line command which is generated by GUI options since sometimes you might want to do some tests in UI and then do a batch converting...
