Let's Unify the Add Menu!

The current design of the 'add-process' differs across multiple modules, which increases the learning curve for new users. My proposal is to extend the use of the Shift+A Menu, and implement it in some other areas. I'll also list some Ideas for improvements to the add menu itself along the way.

Here is the current way of adding a modifier in blender: You have to scan a huge list of all available options in order to find the single component you're looking for, and then click on it.

I think I don't need to explain how much more intuitive the add menu from the shading window is: So, my idea is to get rid of the add button in the modifier panel and redesign it something like this: (Edit: As mentioned in the comments, for consistency's sake, an add button like the one in the node editors and the 3D View would still be necessary, for example for tablet users.)

I used the node window background in this case to have a visual indication that this is a panel to which components have to be added and to encourage the use of shift + a, but ultimately a different design should be used as modifiers aren't node based.

One could even go as far as to add a tool tip if there aren't any modifiers yet:

Once we've implemented it into the modifiers panel, however, it gets a little tricky to draw the line as the constraints panel uses a similar design, and any added physics are essentially modifiers as well.

So I would suggest all following modules should use the shift + a menu:

• 3D View
• Shader Editor
• Geometry Node Editor
• Texture Node Editor
• Compositor
• Modifier Properties
• Physics Properties
• Object Constraint Properties

Let's debate in the comments if I've missed any!

As a last point, I'd like to suggest a few improvements to the add menu itself:

• All the modules that currently use the add menu have slightly different implementations. For example, in the 3D Viewport you can't search through all the options. So I would really appreciate if this would be unified as well.

• The add menu in the node context (so e.g. the Shader Editor) should be able to search through all node options. So for example I should be able to just search "Multiply" and it would show me all nodes with multiply options in them (The mix node and the math node), and when I add them it should automatically be set to that option.

• It would be incredibly beneficial if when pressing shift + a, you could just start typing, and it would automatically enter the search function. Just a nice improvement for speedy users.

Definitely let me know in the comments how you feel about my proposed UX changes!
