Manage materials - bether way

A. Want suggest something like Collection as DIR but for metarials in outliner.

• Then we can organize material by some types under dirs.
• Current Material Properiteis can be for create materials, and any of this after creation can be stored under DIR "Materials" (can be dir as collection box with the material purple circle)

B. Current Object Properiteis panell not offering set material, and this should be changed to allow this then:

• object can select material from outliner by Eyedropper
• from outliner material can be moved by D&D to Object Properiteis
• from outliner material can be changed (then not listing current material, but list of whole materials with three/dirs)

C. Restriction Toogles

• addtional filter as "Material"
• addtional restrition types as "Material" (eg. easy hide emission type, lights, etc)

D. Most of problems what I meet is:

• I duplicated many times this same material
• I creating materials acidentialy very often
• names are similar
• it's hard to delete material with be sure that this not broking something where is used
• the input filed to select material is short
• as we selecting the material by some combolist, can be more like selector of dirs (maybe)
• I have problem with "Variants" options for many material/colours for elements (the point 3. can solve this maybe as way to select what I want/need in curentd type)
• I have problem with stack of renders with variants/options of materials to shedule some FIFO, eg. want prepare some list to do as procedure of render with many colours, etc. (now can be done by add-on and API in relation to point 3 - switching betwen material list assigned to object)
• I have problem with discover which objects using material after Select (now this buten can list in outliner whole object, then functions from point.2 can help to change material from Object Properiteis
• import material can be more easy, and maybe can be used as packed for linked

Need discuss here ; )
