Autocomplete Ace Editor

Is there anyway to enable autocomplete for the ace editor?
The ace editor comes with it as an option now. Is there a way to edit this configuration for node-red.
It should be as simple as:

var editor = ace.edit("editor");
enableBasicAutocompletion: true

Never mind realised you could use "Alt+Space" to bring up the autocomplete window. Would be cool if it was always enabled though.

When you say 'always enabled' what do you mean? Prompting for completions without the keyboard shortcut? That will always be a personal preference - some developers don't like it, some do. Right now we don't have anywhere to store that sort of option, but something to consider in the future.
