Just trying to imagine the workflow :)
I personally prefer a ~32" 4k screen for main work but I could see the convenience of an iPad to quickly remote in and check on stuff or maybe it's enough on it's own and I can learn from ya'll!
Just dock your iPad in the office and get a desktop class experience. Pick it up and go and have your same apps and sessions and data anywhere.
Would be nice. It's the experience I had with a Surface but I get Windows isn't applicable to all users and workloads.
You can use this to fix bugs in iOS apps from the park and try new TestFlight builds within minutes.
The fact that you can't turn off the iPad screen while it's docked drives me crazy.
I recall: using stage manager, plugging into monitor via USB-C, going into Settings to disable mirroring/enable as external display, ensuring you have a mouse/keyboard connected to the iPad, and then just clicking the iPad screen off with the lock/unlock button.
lmk if that works!
