While it has been possible to set secure environment variables from the Solano CLI for some time (see docs here), there has been no way to do it from the app or to see what values are currently set. We have added a new page to Organization settings that will allow Org admins to manage variables that are not set from a config file.
We are also adding a new tab to the report page that will list the environmental variables in order of precedence for a build. This page will display the list of Variables, their scope, and their value stared out. Org Admins will be able to toggle showing the actual values.
