I like it, the dialog is looking good!

I thought about this things:
"Line wrapping" => "Do line wrapping"
"Directory navigation messages" => "Show directory navigation messages"
To add a verb as the first word.

The first two lines, could IMO grouped with a groupbox labeled "Project". But 
thats only a matter of taste.

good work!

best regards
Tobias
