Have to, absolutely not - but you'll find that Emmet is extremely useful for HTML.

Some non language specific ones I use constantly: SublimeLinter, Sidebar Enhancements, Git, Quick File Creator, FileDiffs.

Thanks for the tip on Quick File Creator. I'm a pretty heavy Sublime Text user and that just solved a pain point for me.

Another one that's useful for me in web-related work and not specific to any particular language is the Web Encoders plugin: https://github.com/revolunet/sublimetext-web-encoders -- I often use it when I need to test URL encoding/decoding stuff.
