Thanks. That's good stuff. I ran some of the apps in your Applications
directory. I like the resistor color coder.
It took a while to figure out that where the prefs are being stored -
evidently in username\Application Data\Dabo\DaboPreferences.db as an
SQLite db.
Any difficulty in storing that in my "main" Postgres database as a
certain table? Some settings I need would be particular to the user but
many would be system-wide.
