More contextual information in the inspector and editor

[eon-s]

Godot need some kind of statusbar with information and panels can use some extra indicators in particualr moments.

For example, this is a great addition to the inspector in Godot 4

But there are other parts where similar hints of "context" and "actions" can be added.

There are warning signs when a node is missing a property, like bodies missing shapes, but there are no notifications of where to add those missing elements (can be a pain with particles) and a message like on Controls can help.

Other things that can benefit from that is to know where is the focus on the editor and what action is about to undo, these can be for top/bottom status bar

Now, listing things that can use contextual hints/information related to scenes:

• Bodies needing shapes, the hint could indicate where is the property
• Empty collision shapes
• Particles that need Particles Material or other Resources
• When a selected Camera is not current
• Nodes with transform with a Node parent
• Maybe more

Things that can make use of contextual hints/information related to the editor:

• Next undo action details
• Where is the focus currently (a dock, a panel, the inspector)
• If there is a node or Object data copied (ctrl+c), can show the class stored in the clipboard, or indicate if it is code
• Also more
