I've seen people making a lot of suggestions for the new nameplates that are in the current open beta.
People have their own preferences for what info they want to see on a nameplate.
So, a granular nameplate customization would entail having some way to choose exactly what information to include or omit from the nameplate.
Specifically not the physical layout, but rather hiding or showing the existing information that a user sees on others nameplates.
Some examples could be:
User A prefers nameplates enabled, with minimal info such as names only. They would disable things like status or group banners and icons.
User B prefers nameplates enabled and just group banners with no text. They might disable status and extra text tooltips like group name.
User C prefers nameplates disabled, and uses the quick menu to show the full nameplate info "at a glance". They want to see it all for a moment, but not have it hang around unless they want to check again.
