I was previously not in favor or against making it active by default
because my only argument in favor was a guess that most users prefer
to have it enabled. But after seeing Liviu's ticket (#8589) I talked
with some users who confirmed that they had no idea about this
feature. Another user who didn't know about the feature and a user who
is in favor of making it the default:
http://comments.gmane.org/gmane.editors.lyx.devel/140623
I could not find any other discussions in a quick search.
I now suggest it because of a new argument: it's more likely that {a
user discovers this feature} than {a user who does not like this
feature cannot figure out how to turn it off}.
Would anything need to be changed besides "false" -> "true" in
LyXRC.cpp and updating RELEASE-NOTES?
Any thoughts on enabling continuous spellcheck by default?
