Reduce menu visual clutter by a probe/trigger creation wizard

[mpmxyz]

What is the reason for this feature?
The current UI uses a few highly cloned UI elements to let the user configure a limited set of actions.
Because the UI is almost stateless the user is exposed to too many options which may not be relevant for their next goal. The amount of text overloads them.

Additionally it is hard for the user to associate the goal they have in mind with the given tab it is available in. (example: grabbed objects as a "Slot-Child-Added Trigger")

Describe the solution you'd like

• There should be a globally available "+" or "Add" button that opens a list of possible trigger/probe types.
• Each option should have an icon and a title that is understandable without the tooltip.
• If space allows there should also be a description so there is no need to hover over elements. (no tooltip)
• After selecting an option the user should be led through a wizard style menu.
  • The wizard would only show options required by the action.
• The completion of a wizard should allow for a repetition of the same kind of action.
  • Background: The current see-it-all UI has the advantage of being fast to use. Opening and using a wizard adds extra steps.
• Options only needed when creating a probe/trigger can be hidden away within the wizard pages.
• When leaving the wizard, the tab of the created object should be selected..
• TODO: Some probe default options are needed by probes created from a trigger. How can that be made more readable?
