[Framers] Superscript and Subscript

[A Craig]

I have a few superscript and a lot of subscript markings in my book. 

The markings are especially annoying, particularly in tables, as they don't leave enough space above the superscript so the table line above it so it looks crammed into the space. And Frame rearranges the leading for both so there's too much space between the lines - it almost looks like I have 1-1/2 line spacing. 

I'd like to make the super and subscript markings a little lower and higher, respectively, so they are noticeable, but don't muck with table spacing or leading. 

Is there any place in Frame to control these options?
