I haven't used BBEdit regularly since I discovered Vim (and now Neovim) 10+ years ago, allowing my license to lapse. But I couldn't resist the 30th anniversary sale to purchase the latest version for $30.
The UI hasn't changed much, which is both good and not so good.
Neovim will continue to be my daily driver but I'm glad to support a small, local (to where I live) developer who's been making great Mac software for a long time.
BBEdit is like an insurance policy just in case…
