If a user starts MIOS Studio as they do now, it will be the same as now: it remembers midi in/out devices and path to hex file.
If a user starts MIOS Studio with an argument say "project1" then the following settings are saved somewhere to be loaded next time MIOS is invoked with "project1":
- screen position and size of window
- size of all horizontal dividers
- midi in/out devices
- path to hex file
- any other settings to remember?
- perhaps the argument e.g. "project1" appears in the window title
