That's not that kind of jump the OP is talking about. dumb-jump/anyjump are plugins which allow you to jump to definition / declaration etc. without having any kind of language server running or having preprocessed the source code. They work by essentially grepping through the source code on the fly with some language specific smartness on top to make it work better.
- lack of global search (like ripgrep integration) and something like dumb-jump/anyjump — it's faster and less resource-intensive than running LSP
- I encountered a couple of panics losing my unsaved changes after 24.03 update, most recently yesterday. Looks related to this bug: https://github.com/helix-editor/helix/issues/3501
I can live with no global search, but not with data loss. Probably will stop using it for now.
