1.  Are there hooks for saving gui preferences to the Pd settings file?  I don't see anything

in Vanilla.  Has pd-l2ork implemented those hooks?

2.  What options should be available in the GUI dialog?

3.  How should it update?  Immediately after the user makes a choice?

4.  How should these settings interact with settings from within the patch?  The only workable solution I see is that things should just "work as they work", probably meaning that patchlevel options (which are presumably loadbanged into being) would supersede the GUI dialog settings.  And I can put a "Refresh" or "Apply" button in the dialog so the user can manually override.

Here's a start for the options:

1) canvas bg color

2) font color/size/face

3) text selection color

4) wire color

5) box outline color

6) box fill color

7) xlet color

8) active xlet color

9) link color (for pddplink/helplink)

And also

0) Dropdown list of presets for whatever people might want quick access to like: Ubuntu x.x, Linux Mint, high contrast, inverted from default (black bg with white text).  (At least I don't know a way to get tk to inherit GNU/Linux themes so this would be a workaround for that.)
