Wish 1: It would be very handy if there was an option during Shade mode where the user could tap the Tab key to make only the selected object(s) shaded, while the remaining (non-selected) objects will appear invisible. Tapping again on the Tab key will make the other objects visible again.
Wish 2: Additionally, Shift+Tab could cycle through the display modes. Ctrl+Shift+Tab will do that in the reverse way. Currently, Ctrl+Tab and Ctrl+Shift+Tab double as cycling through the viewports. This means that Ctrl+Shift+Tab could be assigned to cycling through the display modes instead.
