Eliminating the stupid liveries is easy. Just go into Content Manager where it shows all your downloads. Each livery shows as a separate download. Check the offending ones and click the "Uninstall" button at the top. I've done this for all of the xbox and Aviators Club liveries for all of my planes. I don't mind the red, yellow, etc. ones so much.
As for the cockpit labeling, keithb77 recently did a superb one just like you describe for the Bear Studies MiG-15, maybe we can get him to do one for the An-2. Unless the panel is encrypted or something.
Unlike the MiG, the An-2 at least has good English tooltips, so I can live without an English labeled panel, but it would still look cool.
