While I appreciate that there is a LOT of... ...flexibility... ...in being able to separately control the display/override characteristics,
of individual levels,
of multiple models and their reference attachments,
in each of 8 view-ports,
with 3 layers of switching (Freeze,Global, View),
controlled by a plethora of configuration variables,
reference file switches (allow, always, never),
and key-ins to synchronise from DGNlibs or Nested info... but,

it can prove to be the most confusing thing to users, who above all cherish simplicity in their workflows.
This is especially evident when a user is sheeting up and may be juggling modelspace / paperspace, and cant get level overrides/display to synchronise efficiently.

I wonder if there is benefit to adding a switchable mode that simplifies/collapses the multi-model / multi-view / multi-switch scenario to a simpler one-mode-to-rule-them-all control?

I think this would have to be a file based switch, so that it could be applied to specific DGN files where applicable (eg a sheet file that would benefit from a 1:1 mirroring of level control...)
