When automatic spell checking is enabled, there's a 2-3 s lag when you start typing, when the spell/grammar checker is loaded.
It would be great to trigger this loading in a separate thread right when the application is opened (provided the setting is on), so there's no annoying stutter when the user starts typing.
Sounds good -> NEW
With Tor's excellent work in bug 104332, the loading time was greatly reduced, and moved to startup, so maybe this isn't very important anymore.
There's this gerrit change, but not sure if it's going to be finished: https://gerrit.libreoffice.org/#/c/56095/
I'm closing this as WONTFIX, if the change is committed, the status can be updated.
