I am very happy to see such innovative highlighting feature for csv files in kwrite. It would be nice, if common "tab"-delimiter would also be supported.
You can select the TSV highlighting, that will do what you like. You can edit the mode to have other extensions, at the moment it triggers on extensions="*.tsv;*.tab"
Oh, thanks, I never heard that it was called "TSV". Perhaps it would be convenient to rename it like the others in "CSV (TAB)"?
