How to change the currency displayed:
Log in to Sturppy
Click the 🚀 Project tab
From the project settings panel you'll see a field for "Currency"
Delete the symbol within the filed and type/paste the symbol of the currency you'd like to be displayed
This will automatically be saved
Currency can be changed on a Project by Project basis, meaning you can have a project displayed in USD, a project displayed in Euros, etc.
