Touch Type is a nice tool that is still unfinished.
- Can’t select several glyphs at once (not by Shift+clicking, not with a marquee)
- Can’t constrain rotations to 45° by holding Shift
- Can’t constrain movements to axes by holding Shift
- Can’t select a glyph when it’s even partially obscured by another one next to it
- Can’t reset selection to original states via on-screen controls
- Snap to Glyphs obviously doesn’t work with it (imagine if it would have)
- There is no way to apply changes to one glyph without shifting all glyphs to the right (relative/absolute mode) — previously reported at https://illustrator.uservoice.com/forums/333657-illustrator-desktop-feature-requests/suggestions/34552057-make-the-touch-type-tool-work-both-sides
