I think maybe too many changes have been rolled into one here. The bulk of the changes seem to revise the input and feed pages, these changes can be seen and used without the device module even being installed.
IMO this button should be labelled “New Input and Feed interfaces Beta (with Device Module integration)”
I like the “Beta Features” way of doing things, it’s much better than switching git branches and more likely to attract early adopters if there is a easy way to switch to and if necessary, back out of new features. Although I wonder how long things will remain in beta with this feature, perhaps it should be called “Feature selection” and used long term to switch between options, some of which can be marked “beta” until such time as they are merged into the core, dropped or just no longer beta but remain optional.
Since my initial observations do not relate directly to the “device integration” but are more about the new input and feed interfaces, I will start another thread and possibly come back here when I’ve tested the actual device integration side.
