[[ https://developer.blender.org/T54987 | Implement Multi-Object Properties Editing ]]
**Implemented**
- Visually show for properties, which are supported for multiple object at a same time (e.g. when hovering on the property)
- Alter the `Alt Key` behavior e.g. now if multiple object are selected, try first for multi editing when no `Alt key` is pressed and when editing begins with alt only effects `Active` object
Demo

**In the demo you can see:**
- Show property normal when no multi-property editing supported
- Show visual affordance when property supports multi-editing objects
- When `Alt` pressing and executing some event (clicking or dragging) on property, property becomes normal
- If multi-editing property, without `Alt` affect all selected objects
- If using `Alt`only effect active object
