After lots of changes I have switched the code permanently to the new sequence model. It saves about 170 lines of code in the sequence-page source. There is some potential to save more though.
I also did more work on state persistence. A song now contains more information (selected machines, pattern, options) and these things are restored when loading a song.
Another good change was moving the song-unsaved flag from the song (core-library) to the edit application. This make the core library more light-weight. The editor application can now determine whether there is something to save by combining the unsaved-flag and the undo/redo stack. The unsaved-flag is still needed as I feel not everything needs to go to the undo/redo stack (like selecting a machine). Undo/redo looks quite complete now. I found a solution for my last issue, although I am still not entirely happy with it.
I also made a few startup time improvements. Found a weird issue with the interaction-controller library probing joystick devices. One ioctl on joy devices for hdaps devices is hanging for quite a bit.
Finally I did a huge cleanup on or somewhat uncommon header file setup. We always had a header declaring the types and one the methods. This helped with include conflicts. But now we have 50% less files to care and I just needed 2 forward declarations.
Again several bugs were fixed. I will check remaining reported bugs and hope that everything is fine to consider releasing 0.6.
