I propose more consistency in Revit. I think it would be a huge improvement to work flow and efficiency if different tools and features worked the same way. This way, we could solve our specific goals without having to memorize the unique ways a tool or a feature works.
Walls and Columns. Both are usually load bearing assets that have height parameters. A generic architectural column will even pick up on the wall composition of an adjacent wall. However, only a wall can have an unconnected height. The height of an architectural or a structural column can only be adjusted based on levels in the project. Just add an unconnected height option to columns. Such a simple fix here.
I do not think this is a big ask, and is a small feature that will help tremendously. One more small step on the path towards a more consistent program.
