Add a Jewish (Klezmer) Scale and a Possible UI improvement suggestion

A few of suggestions.

  1. Pop-up dialogs are by convention, often closable with the Escape key. Escaping as a rule normally means do not proceed but it can also be followed with an Apply/Cancel type confirmation if in fact the dialog has a save type button on it.

  2. Any chance of adding Klezmer/Jewish scales? These are currently present in Native Instruments (where they are referered to as Jewish scales).

Move Latch functionality out of the menu, and to a an area where it can be quickly and directly accessed (next to the performance selector for example), as this is often used only periodically while making selections but not while actually programming. By the way, THIS woulds be an excellent place to have it come up in a right click context sensitive menu over the PERFORMANCE button, if space is limited.

Thanks!
