- Replace the blank option with an italicized option that's the current
default language, if there is one selected with "default" label.
- Make the "text" option more informative by adding (no highlighting)
to the label.
- Remove the hint for "text".
- Prioritize as left to right, before start typing:
blank/default language, text, quote, spoiler, math, everything else...
