Dwell. Double length of time to select letters.

[willwade]

Eg. Hello. Requires two L letters.

We need to allow repeats on letters but maximum twice.

To avoid this happening too much by mistake what about if we only allow it to work on certain letters. Or don’t let it occur on letters that dont occur as doubles.
