All graphic overrides that are available in any other view should be available in legends. Linework isn't available, show hidden lines is available but doesn't do anything.
I think we should combine all of the "Legends" wishlist items into a single idea: IMPROVE FUNCTIONALITY OF LEGENDS! I'd like to be able to rotate legend components, override by category, and tag legend components... and copy them to other projects!
Thanks for taking the time to submit your idea. Unfortunately, this idea did not get the support of the community over the last 6 months and as such we will not be pursuing it at this time. Please feel free to rework (titles and clear descriptions are really important) and resubmit this one down the road.
