First Launch

When you first open Nipper, you’ll see an empty allocation view - a blank canvas ready for your routing configuration.

The interface has two main panels. On the left, you’ll work with audio sources - this is where you add your audio inputs. On the right, you’ll see video destinations, where you add your video outputs with embedded audio.

The bottom status bar keeps you informed with three key pieces of information: your configuration status (whether it’s unsaved or shows the file path), Routing Check results showing any issue count, and your license status (✓ Licensed or ⚠ Unlicensed).

Initial Setup

Default Author Name:

Menu → File → Edit Author

Enter your name as the default author for new configurations. This will populate automatically when creating new configurations, though you can change it for individual configurations later if needed.

Theme Selection:

Menu → View → Light Mode / Dark Mode.
