I don't get this Sublime is dead nonsense. It's still being updated and works great. It's been my editor of choice for years and I happily pay for my license. I'd probably pay more if they asked me, it's tremendous value for money in my opinion.
With that being said, just a quick look at, for example Stack Overflow 2025 survey tells me it doesn't have the same mindshare it once had.
There needs to be a critical mass of people using it for things that aren't core to stay updated
The key plugins I use are some LSP servers, and they work wonders. The few languages I mainly use (yaml, json, TS/JS, python and Go) I get great language support for via the LSP servers and the editor is blissfully fast always.
I could live without even the LSP stuff, but the one feature I can't live without is Sublime's excellent recovery support. Every once in a while my system will crash, and even though I've had multiple unsaved buffers Sublime recovers them every single time. Saved my butt more times than I want to know!
