Extend Autocomplete Options

[edwillys]

Hello,

Is it possible somehow to make the autocomplete a bit more flexible. I have 2 use cases in mind:

1. Extend the short names for certain emojis. For example different smileys could be referenced by ":)", ":D", ":(", etc...

2. Add an option for "contains" keyword instead of "starts with". For example, ":br" would return ":flag_br", among others, if any.

3. Similar to above but with case sensitiveness.

Thanks in advance.
