I did some small graphical update to the Calligra Suite following the excellent mock-ups from @manueljlin

The biggest problem that i had with calligra before is the lack of proper Bi directional text support, making it unusable in my language :(
@sohrab @manueljlin yeah that's not suprising :( I'm hopeful that modernizing a bit the UI will encourage some people to work on the rendering
