Case change and shift options
1) Four CASE CHANGE options would be HUGE!!!
2) Lock for numerical alt characters...as in making quotes and 3 successive exclamations—" !!! "—easy breezy.
You can hold down shift to type " !!! " or similar.
What do you mean by “case change options”?

But you can't type the following text...
" !!! " by holding down shift - only gets to the space after 3rd ! Then drops out to single quote at the end.
UPPER¸ lower, Title and Sentence are the four standard Case Change states offered for selected text - Arrow Text app had them piggy backed onto their keyboard display...SO handy.
