I use emojis for an unofficial sort function. Every similar themed project gets the same emoji at its beginning. This really helps to quickly find the project or the team you need.
It is also amazing for the search / link function; The emoji can help you quickly recognise the required project among many with very similar names.
Here is an example.
The only problem is that asana currently only supports a few emoji’s in task, project and team titles. Even the emojis ’s that do work are fairly obscure.
That is the community post about it.
