Most users that have been using the Stairs tool found it to be the one most horrible tool in Revit. It is totally non-intuitive, non-native English speakers are having troubles with all the parts' names and their dedicated families. You have to open several windows to set various options and sometimes you are wasting a LOT of time just to find the right setting.
Autodesk Library contains no Metric Balusters , Posts, Railings, and other profile families for Stairs, which is quite sad situation. I have to change all such families to metric, creating multiple metric types and testing each one of them.
Stairs tool should have a tabbed interface, something intuitive like Steel Connections have. And MOST IMPORTANT, the stairs should automatically update/reset when changing the calculating rules. You change the calculation rule, you delete the existing stair and recreate it again just to find out that the new rule still doesn't do the job right . Come on , Autodesk, the preview window should highlight each part , just like the Steel Connections preview does.
And final consideration: Stairs are ALWAYS a structural element (load-bearing element). Please create separate commands for Structural Stairs and Architectural Stairs, just like the Walls commands are (WA / WS).
