📄 Context

Issue tracker. Currently, it shows the inputs by default, and as a `tree view, ' you can peek inside and check for notices/reports/vouchers and take some actions like executing a voucher. The idea is to keep the current app's input listing and add specific views based on input types (it will need a connection to the Application's GraphQL). That will also serve as inspiration when the output unification comes out.
