I understand that you've previously contemplated starting with an empty preset list that can be maintained similar to the Scene and Source lists. This would allow fewer/more presets and flexible ordering. While I upvote that idea, I'd like to propose taking it to the next level.
What I had in mind was refactoring the preset list as an "action" list, supporting multiple action types, each action type configurable with the supporting values it needs. Calling a preset would, of course, be one action type, supported by a configurable preset number. A second action type, which sort of drives this proposal, would be calling a scene, supported by the scene name. Given the complexity with which scenes can be constructed, this would be an enormously powerful feature. For example, it would enable camera changes with transitions from the ptz control pad. (Confession: calling raw presets without transititons to mask gross camera movements is too risky for my workflow.)
One can imagine other action types with potential for lots of extensibility. Think about an action type that issues a generic camera command, configurable in the settings. Or many OBS commands, for that matter (though I urge caution about getting too distant from camera control). Down the road, one could even support a multi-step action type--one that issues a sequence of actions, similar to what Stream Deck and Companion support.
