Consolidate block selection UI for Display properties to Multiblock Inspector
Case 1: Open can.ex2; apply; change representation type to Volume. Search for "block" in the properties panel, you'll see the following:
The Extracted Block Index allows you to pick which block to volume render.
Case 2: Open can.ex2, apply, close render view, create Spreadsheet View. Search for "block" as before, you'll see this:
The Composite Data Set Index UI is the way to select the block to show.
Case 3: Open can.ex2, apply; open View > Multiblock Inspector. The multiblock inspector shows the following:
This is the UI to select which blocks to show.
Proposal: We consolidate the two way of setting blocks to show -- using Display properties panel, and using the Multiblock Inspector. We remove the block selection UI from the display panel and have users always use the Mutliblock Inspector.
Since the hierarchy can be large, a small widget embedded in the properties panel can be tricky to use except for smaller datasets. Having a separate panel for that make it easier to navigate.
Note: This does not affect filters or readers that offer block selection e.g. Exdus Reader Extract Block. Such filters will still show the block selection UI on the properties panel. The Multiblock Inspector is controlling display properties for the data in the active view and not filter paraemeters.
