Bug in "Baseline Shift"
Open Pages or Keynote. Select multiple lines of text. In the "Format > Text" pane click the gear just above "Character Styles" to access "Advanced Options". Change the "Baseline Shift", making it negative, aiming to bring the lines closer together. Instead the lines incorrectly get further apart! Clearly a bug.
I'd also prefer if "Baseline Shift" and "Character Spacing" and "Superscript" and "Subscript" where immediately available in the main Text panel, without having to make so many clicks.
