The Properties Editor is for editing the settings and properties of datablocks in Blender.
The properties can only act on one item at a time. If you've selected five objects and want to change the same setting across all five, you've got to jump through hoops to make it possible:
Either, you can use the Copy menu to copy settings from active -> selected (only works for a few settings)
You can also right-click and select Copy To Selected, which copies the given setting from active -> selected
Here's why this is a problem:
- Having to right-click and select Copy to Selected on every property every time you change it is inefficient, and not fun
- It doesn't work for some things, like adding modifiers, setting up rigid bodies etc
- It's quite complicated solution and is hidden
- Some tools have been added to work around this limitation (Rigid Body Tools) whose only reason for being is to apply certain settings to multiple objects
Make the Properties Editor act on multiple selections. Display a '-' symbol for settings that differ, and display the value for settings that match.
- No need to right-click and select a menu item for every single property change
- It's clearer and simpler for the user
- This way we don't need separate 'tools' such as Rigid Body Tools just to apply settings to multiple objects
