I am trying to install the Salesforce widget library but it is a .jpl file. There is no way to import nor is there an instruction page on how to install a .jpl file. This app is unusable for me at this point.
Figured it out. Apparently you have to start creating a new prototype first before you can install a widget library. Not very intuitive but the immediate issue is resolved.
You're right, that might not be the most intuitive way to do it. We might consider changing that in the future.
