Tiny workflow improvement: labelling the phrase bank with hexadecimal instead of decimal?
If you want to use the Zxx command and take a quick glance at the phrase bank, you have to translate those numbers in your head.
If the phrase has say, a number like “11”, you would write Z0B.
It’s a source for mistakes, IMO. I know that you can also use program changes, in which case it can be debated if decimal is a better representation. But I’d argue that we should encourage the use of Zxx whenever possible, because it’s better 
It would apply in three places: the instr. macro device, the lower panel in the instrument editor and the instr. properties panel.
