Emotify
In the add-on you create rules that will automatically emotify events. For example the events Football and Afterwork drinks will be emotified to ⚽️ Football and 🍺️ Afterwork drinks.
By doing you will increase the overview your calendar gives you. TJ VanToll calls it a "Life Pro Tip" on his blog.
Other actions: duration, location and start/end time
Events are often quickly created. They often end up un-enriched while it is definitely handy to have the correct duration, location, etc... With Emotify Events you can set those properties to automatically apply for certain events.
