The Edit Details page for each layout has a long list of configurable Actions like Send MIDI, Start Tempo, etc. These can be set to trigger on Song Selection, or with a gesture like Two-Fingered Tap. Some of these functions are very popular, but many people don't look for them in the layout settings, or they set them for a layout and then change to a different layout and don't know why the functions stopped working. So I'm thinking of moving them out of the layout level to the app settings level, where they would work consistently regardless of what layout is used.
The current arrangement allows you to set up different sets of functionality for different situations. For example, you might want to start the tempo function automatically in your performance layout but not in your practice layout. Or in my case, I have a layout that auto-plays through the recordings, which I only use while driving to a gig. A new arrangement would require a trip to the settings pages to change things like that, as a trade-off for making all these settings easier to find and understand.
Do you currently use different layouts to toggle the functionality in this way? If there are a small number of common use cases, maybe I can make those settings more easily accessible from the set list view somehow. Otherwise I think it will be worthwhile to make the layouts a more purely visual consideration (a "layout" as it were

) and move their functionality to the app settings.
BTW I think these settings would still not be synced across devices, so you could have different behaviors on different devices, which is how the remote control settings work.
