maybe there's already a way to do this but I can't find the option. can I disable autocompletion on text files but keep autocompletion on other types of files (like C++) for example: when I type "Local" then hit return I don't want the editor to lower case that to "local" for me.
We tried to improve that completion behavior. https://invent.kde.org/frameworks/ktexteditor/-/merge_requests/747 That should help in such cases and I don't think we should aim to allow to deactivate it fully.
