PS7: interestingly after closing/opening the UECIDE the hovering drops to ~1sec, opening files 1-2sec (caching in java?)
PS8: I would suggest to have font/color etc settings global, not to be set for each window opened..
PS9: When opening large project (ie multiwii) I see only one .ino file and 3 header tabs. Orig IDE shows all 11 .ino tabs (plus .h files) in single editor window
