Please give us start and end indent properties for handrail support spacing. These would operate rather like the equivalent properties on a 'Divided Path', although I guess they'd need to be type properties to be consistent with all the other handrail properties (Oh, how I wish most of those were instance properties in the actual railing).
Currently Revit sometimes puts supports exactly on the start and end of the handrail, depending on which spacing option you choose. This occurs even if you have a wall extension, which is patently absurd. It also occurs on free end handrails, which mean that the support is only half fixed to the handrail. Yes, I know that we can unpin the support and move it - but I have to do that for every single railing, as they are never, ever how I want the supports; clicking the 'Reset Railing' button, loses all the hard-won manual repositioning on the whole railing - with just one little click.
I would also like to have checkboxes that tell Revit whether to include the length of the extension in the support spacing calculations (for start and end) - sometimes you want it included, sometimes not.
