Love the input and didn't even know about the debugger mode
The preset triggered this:
[iNFO: alfred.workflow.input.scriptfilter] Processing output 'alfred.workflow.action.script' with arg '{"action": "load_preset", "preset_name": "feetup"}'
But right after that I found in the documentation that I can create a hotkey, set text input to preset's name (in this case feetup) and connect it with the Run Script bin/bash that the other hot keys are connected with. Works like a charm and might be of help for others
Thanks for your help!
