Added not yet working version of logging / log replay, fixed ALL bugs in main window, enabled full persistence in main window and serial link.

Improved line chart, brought back movement on HUD (but still looks somewhat wrong on the dials). Fixed logging for ground time mode

Substantially bugfixed and improved deactivation/activation and persistence of widgets. A lot of testing of Google Earth view, only minor improvements

Significantly improved plotting, now capturing data in linechart allows limmediate processing / analysis of the whole flight

Improved runtime performance, currently hunting down a bug where the whole application gets repainted although only parts of it are refreshed
