Dataframe view: column visibility editor

[abey79]

• Add hook to SpaceViewClass to allow adding "stuff" to the view title bar
• Use it to display a list of check box for visibility control

Concept:

• Icon next to the component to hide the column

• To unhide (and also hide) use the btn in the title bar:

Decision making update: Separate UI for visibility of components from visibility of components. Implications for now:

• It is only possible to add/remove entity via entity path section. This means there is no implicit show/hide functionality for entity (unless all components are hidden from one entity).
• Visibility of components is only defined through show/hide UI. It is not the same as add/remove, neither it is connected or united with the entity path filter (so instead of having an option to ‘add/remove component AND hide/show component, to only use the latter for interacting with visibility in the UI. what exactly does it mean via DataOut-don't have an opinion there, but whatever it is - to only expose it as one action) :white_check_mark: Pros:
• Reduces complexity
• Decoupling query from looks (if the show/hide is looks?)
• Smaller changes will allow to add value faster (instead of coupling it with entity path etc)
• Also valid for entities as rows in the future! :x: Cons:
• Does not help forming a mental model for our data model through UI (hierarchical relations between entities and components (soon archetypes))

How? Icon in the header of the Viewer :white_check_mark: always visible! :white_check_mark: no awkward interactions! :x: a new interaction pattern for the viewer!! :x: what if there are few tabs — might be weird if it appears/disappears

We'll embrace this weirdness in the context of an already seriously weird view and see how this feels/how users react :)
