Development Update

Development paused on FFAB until the community starts hitting me with bugs or feature requests. The current version of FFAB works great for my personal requirements, but I'm happy to put in more work if folks want / need more.

There are two large updates waiting for community green-light:

• Node Graph UI: Existing DAG code can handle it, the UI 'just' needs to be built.
• Video Filters: Also doable... duplicate the Audio Filter code, dream up UIs, then test.

Both are interesting, but (a) I'm an audio guy, and unable to exhaustively test video filters / unqualified to suggest video-centric UIs, and (b) the Node Graph UI is just a different way of visualizing the existing linear filter chain, so feels somewhat redundant (except in the case of ASPLIT parallel routing, where seeing nodes + cables would make sense).

With enough demand, I'll fire up the boilers and build.

FFAB Overview
