Ask HN: If building an IDE from scratch, what features would you add?

2•rajasimon•10mo ago
Many IDEs feel bloated or outdated. If you could design one from scratch, what would you keep, drop, or reinvent?

Comments

I'd keep all the features from neovim, remove all the features from every other IDE.
joegibbs•10mo ago
Native vector search would be great. I was just thinking today how irritating it is to try to find some specific component in a very large codebase without knowing exactly what it’s called already.
SvenL•10mo ago
Great debugging capabilities, time travel debugging, data break points, attach to running processes, remote debugging etc.

I think the most important feature for an IDE is debugging - at least this is the feature which separates an ide from just a Text Editor
