I recently started adding petite caps to my font and have discovered a few small peculiarities in how they are handled in the program compared to small caps.
By default, a generated .pc glyph has its case set to Upper compared to .sc glyphs that are set to SC.
There is no central place to view all .pc glyphs, though they can be sent to the Small Caps sub category by manually changing their case to SC.
The glyph generator button in the Small Caps sub category can generate .sc glyphs but not .pc glyphs.
There is no separate sub category where Petite Caps can be exclusively found.
I believe the following changes should be introduced.
.pc glyphs should have their base case set to SC or to a newly implemented PC case.
The Small Caps language subcategory glyph generator should either gain the ability to generate .pc glyphs in addition to .sc glyphs, or have a separate Petite Caps sub category created for them where they can be generated.
