P: LrD v10 Hold to Hide/Visibility toggle issues with using Classic Workspace

The option to use LrC-style panels in LR Desktop feels like it was implemented in a rush without sufficient  UX/QC testing. I've already discovered two rather critical issues with it:

• Not all panels have "hold to hide" buttons. Curves and Color Grading are both missing them. Furthermore, some other panels' buttons aren't mapped correctly (e.g. the Basic panel's "hold to hide" button also affects the Curves panel)
• Keyboard shortcuts aren't remapped, so the Cmd/Ctrl + [1-9] shortcuts now open panels out of order, and only if they exist with the same name (e.g. Cmd + 1 is useless now)
