PipeFlow

Python dearpygui based patchbay interface for PipeWire

Intended to be an easy to use graph of nodes, with more power than a traditional list but focusing on QOL options instead of advanced controls and effects. Vaguely based on https://github.com/stuin/pipeflowQt, which was originally by Oskude
