There is an emoji called :man_shrugging: π€·ββ. The name is long and tedious to type. I would like to be able to enter it using a shorter synonym, such as :shrug:. Alternatively, it would be nice to have a drop-down list of emoji suggestions which is triggered as soon as you type :<letter>, similarly to Telegram.
On a broader scale, it would be nice to have configurable snippets, similarly to Sublime Text.
