Here is a trivial issue, but I’ve been bitten before: in the Library/Font Styles… dialog, there are two separate items for “Gradual Tempo Text Font” and “Immediate Tempo Text Font”.
To make these easier to find, and avoid confusion, may I request that these be labeled something like “Tempo Text Font: Gradual” and Tempo Text Font: Immediate"? Earlier, I would look for these under Tempo, and get confused.
