Options Editor as second application

[fire-eggs]

I'm considering implementing options editing as a secondary application. I.e. not as a dialog box in the "main" app.

Pros:

• Keeps the main app smaller
• Setup app can be updated separately
• With preview capabilities in the setup app, user can experiment without messing up the main app

Cons:

• Need to keep the two app versions "in sync" [available options, options format]
• Main app must always re-load options after the setup app is invoked, OR the main app must always be restarted for option changes to take effect
• Project complexity

Setup could keep the "original" settings to be able to restore on cancel. Or maybe an undo stack?

An alternate to preview in the setup app is to force the main app to reload settings, so the user can see "live" changes. But since some changes might not be visible in the current state of the main app, a preview in setup does have benefits. E.g. changing the nav-box color is only visible in the main window if the current image goes outside the bounds of the main window. E.g. changing the overlay color is impacted by whether the current image is light or dark.
