@kommen yes will raise an issue or pr about the multi-line repl. Thinking this could be either a command you can toggle or a :variable on the Clojure layer itself, with the default to be the current single line expression. That would give easy access to those who wished to have a multi-line repl, but not force it on others who are used to single line.

It seems like your original pr would benefit from a complete replication of the vim insert commands available in the REPL history buffer available in vim normal - https://cider.readthedocs.io/en/latest/using_the_repl/#key-bindings
