-/* The caps word concept started with me @iaap on splitkb.com discord.
- * However it has been implemented and extended by many splitkb.com users:
- * - @theol0403 made many improvements to initial implementation
- * - @precondition used caps lock rather than shifting
- * - @dnaq his own implementation which also used caps lock
- * - @sevanteri added underscores on spaces
- * - @metheon extended on @sevanteri's work and added specific modes for
- * snake_case and SCREAMING_SNAKE_CASE
- * - @baffalop came up with the idea for xcase, which he implements in his own
- * repo, however this is implemented by @iaap with support also for one-shot-shift.
- * - @sevanteri
- * - fixed xcase waiting mode to allow more modified keys and keys from other layers.
- * - Added @baffalop's separator defaulting on first keypress, with a
- * configurable default separator and overrideable function to determine
- * if the default should be used.
