[Feature Request] Autocomplete for available tokens

[amcdnl]

Feature Request

First off, love the project. Been looking for something like this for a while now.

One thing I've been playing with is the ability to add autocomplete for the available tokens the user could insert.

Implementation

I was thinking it might be possible to do something like DraftJS Mention's plugin does: https://www.draft-js-plugins.com/plugin/mention.

Considerations

I'm unsure how one would trigger the suggestions since {{ is a pretty complex situation. One thing that might be better is a + button or a command like CTRL+SPACE to trigger the menu and then it would add the brackets on insertion?.

Microsoft Flows has a button to (this uses draftjs w/ tokens btw) add the token.
