Neither Claude, OpenAI, nor Gemini let you do either, so it's not ubiquitous.
You can't delete messages, you can't branch, and you can't edit the LLM's messages. These are basic, obvious, day-1 features I implemented in my own LLM UI that I built over 3 years ago, yet I'm still waiting for flagship providers to implement them.

It's pathetic how rare good UX is in software.
Can you list some UIs with these features?
