hot take: I *really* liked the floating panels in UI3. 🌶️ Floating panels made the canvas underneath feel expansive. Like clouds floating over a vast landscape. Fixed panels make me feel like I'm viewing the canvas through a fixed window. Like I've got snorkel goggles on.

My take is that “Floating panels”made the information presented on them difficult read or use due to very little area and constraints on the panels, thereby causing a learnability problem (cognitive overload) and directly impacting user efficiency.
