The Developer-Mode Dashboard for Superfluid solves several problems for developers working with the Superfluid protocol:

Ease of use: The dashboard provides an easy-to-use frontend that lets developers create, update, and delete streams on their local Superfluid instance.

Simplification of stream creation: With the dashboard, developers can specify the token, recipient, and flow rate in a more intuitive format (tokens per month), rather than using complex and unfamiliar units like wei/sec.

Streamlined development workflow: The dashboard integrates with local Superfluid and Subgraph instances, making it easier for developers to test and debug their code locally.

Overall, the Developer-Mode Dashboard helps developers work more efficiently and effectively with the Superfluid protocol, reducing the time and effort required to create and manage streams.
