Your Stream Deck, live in Affinity.
Deck Controls puts Affinity on your Stream Deck keys and dials, with real values on them: the selected layer's opacity and blend mode, what Undo will undo, whether a layer is showing. And any script from your Script Library, one press away.

// what it does
What's on the keys
Layer opacity
A key sets a fixed value. On a Stream Deck + dial, turn to change it, push for 100%, tap the screen for 0% / 100%.
Blend mode
Set one mode, cycle through your favourites, or scroll through every mode on a dial. The key shows the current mode.
Undo / redo
The key shows the step it will undo or redo. On a dial, turn to step back and forth through the history.
Show / hide
A live eye for the selected layers.
Run scripts
Any script in Affinity's Script Library, or a .js file: converted Photoshop actions from Action Converter, Content-Aware Scale, your own.
Always current
Keys update as you work in Affinity, and say what's missing if Affinity isn't running or nothing is selected.

No. Every action works on keys, on any Stream Deck, including Stream Deck Mobile. Dials (Stream Deck +) add turning and live values on the touch strip.
Does anything leave my computer?
No. The plugin talks to Affinity over your computer's local connection only.
