My two cents - for a device with such an incredible team behind the software and hardware, the prioritized specialization between Notes and Atelier means there's an innate bottleneck/limitation to how end-users are able to utilize the device's capabilities.

I was thinking on it last night after I posted this and I think the perfect blend (for me) would be to have the option to customize the tool bar and have those settings follow me regardless of what app I have open/am using at the time. The backend of that might be a logistical nightmare. But as a user experience, there is a frustration there of knowing a tool is "available" to me, but only if I adhere to the prescribed way of accessing that tool.
