I've developed a Sprint Layout Plugin Manager that allows you to manage and run multiple plugins from one convenient interface.
No more redefining plugins each time you want to use a different one — simply select the plugin you want from the list and run it directly.
Main Features

Centralized plugin list – Manage all your Sprint Layout plugins from a single location.

Friendly names – Assign easy-to-remember names to your plugins.

Edit paths & rename – Quickly update plugin paths or rename them without touching the configuration files.

One-click run – Double-click or press Enter to instantly launch the selected plugin.

Automatic forwarding – Correctly forwards the plugin’s result back to Sprint Layout (supports exit codes 1–4 & 128–255).
🪄 About screen – With a fun touch: “One plugin to rule them all!”
How It Works
Place the Plugin Manager executable in your Sprint Layout folder.
Add your plugins once through the UI.
Select a plugin from the list and click Run (or double-click it).
If the plugin produces output for Sprint Layout, it will automatically close the manager and return the result to Sprint Layout.
