also, case changing asr presets included in plugin package don't use asr defaults for exception words (i've changed these presets to use explicit exception word list instead of defaults). if you want to use asr defaults from 'change case' command, copy preset and change "replace by" from, for example:
\@tc[[$1;;\@1]]
to:
\@tc[[$1]]
it's for 'title case' preset, the same change for other presets.
i'll remove "set asr defaults" for exception words from 'change case' command, but all other asr defaults from 'change case' command must work as expected.
