Just a few minor improvements to the Scalculator Ultimate Edition:

• “Menu” support to bring up Preferences, rather than that ugly button.
• Formula and Notes in the display

Of course, lots of code cleanup and refactoring as I go through with an eye for both cleaning up and planning future features.

Hopefully, I will get the “touch” stuff working next, so I can incorporate “reverse lookups”. The idea will be that you are presented with a blank “instrument”, tap in a few notes, and the Scalculator will present you with possible matches.
