Here is an excellent diagram showing the anatomy of a complex staircase:



When I talk about open tread here is what I mean, notice how the tread typically overhangs the staircase and the skirtboard is then applied below the treads, whereas with a boxed in stair case the skirt board is above the treads:



So I basically I want to add in an option for open treads (both, left or right) and also the starter step or bottom tread extension for turnout and volute type handrails, yes this is a can of worms for sure, but it is all very doable.

If I enable some turn outs and volutes I will need to adjust for these but also I need to provide some additional parameters so one can fine tune the placement of the handrail and its termination:

Tutorial 56 - Flared Stairs (4:53 min.)

First look at an inverted T-Shape staircase with a straight and a curved flare:

Since I've been focusing on updating the stair module the last week I've had quite a number of requests for various things.  One request is the ability to flare out the bottom of the stairs.  I can add in this functionality however to start with it would be very rudimentary (just a modification to the treads and risers as shown):





I'm not entirely sure how one would go about in-fill framing the flared portion, nor do I think there is any established or standard way to do this, I could be wrong.  Any thoughts or ideas in this regard?   I should probably ask first if this is something that you would all want or even need.
