In my experience, it's very slow and clunky, but the real problem is that it attempts to impose a lot of styling and decoration _on top_ of the terminal.

For example, the command prompt isn't just a command prompt, it has this silly chevron decoration with autocomplete functionality. It can probably be turned off in the settings, but I find it to be a really annoying default. It just assumes I don't have my own prompt how I want it or my own autocorrect system.

I have to explicitly disable half the 'features' before I get anything actually useful to work with.
