// The assistant: a round button in the bottom right corner opens a chat. Each
|
||||
// question goes with what the panel shows - the tabs, the active pane, the
|
||||
// text of its terminal or its list of files - and the answer streams in.
|
||||
// Commands the model suggests come as ```run``` blocks with «Выполнить»: a
|
||||
// click sends the command to the active terminal, with the user's rights.
|
||||
// Off until the user turns it on in the profile.
