@PeterJones said in Missing .CSV Save As Extension:
With all that said, there is another option (literally): if you are opening lots of files that have no extension to start with, you might consider changing the Settings > Preferences > MISC. > Set Save dialog file extension filter to .* instead of .txt for Normal Text option, which will make the default Save As type as . instead of *.txt, so then you can default to typing the extension for plain text files.
As someone (“bReathl3sS”) points out HERE it appears that setting is going to get a tweak soon. Not sure if that impacts anything said right here, but I wanted to point it out for future readers, in case it does.
