RFD: Inspector+Hierarchy as a singleton-per-window

[zxq82lm]

Inspector appears to be a singleton per window (panel content). To instantiate this single inspector per window, there are three approaches:

• KDL-defined at load time.
• Not KDL-defined at load time:
  • (for example: drone): when you double-click on a graph, there is no inspector, so the inspector is instantiated at this moment [display issue: the inspector takes up the entire window].
  • "Create Inspector" (Command Palette) [same issue as above].

Open questions:

• Is the "Create Inspector" command in the Command Palette is functionally relevant?

Suggestions:

• Should we require an inspector to exist by default in every window?
  • In that case, there would be no more inspector KDL field, and no more "Create Inspector" command.
• Since there is only one inspector per window, maybe in terms of UI it should be exclusively a permanent sidebar that the user can show/hide?

Since there is only one inspector per window, maybe in terms of UI it should be a sidebar that the user can show/hide (enabled by default in every Elodin window)?

Current UI behavior:

• A selection (single click) on Graph opens the Hierarchy and Inspector in the sidebars (left and right), with no way to hide them afterwards. The Inspector also doesn’t open on that graph; you have to click the graph again to get the Inspector with the correct data (in this test case, the inspector needed to be instantiated).
• A double-click on Graph opens the Inspector.
