Editing Multi Object Values and Modifiers

This is an astoundingly straightforward thing. When multiple objects are selected in object mode then the modifiers and attributes that are shared among objects should be editable for all of them at once. Currently Blender only edits the last selected object (highlighted in a brighter orange than the before selected objects by default). If attributes or modifiers need to be transferred over to another object then the objects need to be either instanced or the attributes copied over.

This has some obvious downsides to it:

• Instanced objects also share the same mesh which is only in some cases the thing the artists wants to do
• Make Links copies over the whole set of selected attributes. While this does have advantages it still severely limits the functionality to an “all or nothing” approach. Copy all the things or leave them be.
• One thing is there that’s not too widely known because it’s rather hidden: The Alt-Enter Shortcut. When multiple objects are selected and there’s an input in a text/number field confirming the Input with [Alt-Enter] transfers the value over to all other respective fields of that type (from the selected).

This is in theory pretty close already BUT it doesn’t work everywhere and it works inconsistent. Also you cannot see if values are actually shared or not.

How I think it should be ideally: From my perspective there are applications that do this very well already.Over the last years Modo, Maya and Unity have been programs I've working with a lot and which are good examples for how it can work very quickly:

It’s a pretty straightforward process: When multiple objects are selected all the shared attributes are displayed in the properties panel. When there are values that don’t match the respective input field shows this with an indicator like: “---” instead of a numeric value.

Changing a value sets all the respective values of the selected objects to the input.

If there are * attributes or modifiers * that are not shared by all selected objects then only the shared object attributes/modifiers are shown and an additional Textfield indicates that there are additional values that aren’t shared by all selected objects:

Adding a modifier also adds this modifier to all selected objects. And it adds it on top of the existing ones, not replacing anything existing on the object.

Lastly renaming either renames all to the same name (not ideal in Blender) or renames all to the same name adding an increment number to the previously selected objects by a given rule - be it order of previous selection or order of current list in the hierarchy, or simply by current alphabetical order.
