I don’t know about the rest of the world, but vi is my life. I love this editor and have been using it over 15 years. When you have to make a lot of changes fast in a text file, vi is the way to go.
Do you think you can enable vi commands to be used in the sql nav editor? Even some sed commands to enable editing?
Unix good, windows bad
I would bet most of your largest customers use vi a lot because the largest oracle environments are probably on some version of unix.
