I would love to see expanded snow loading capabilities that let you apply different load distributions that are enveloped for design. Specifically for gable roof structures, ASCE 7 requires that you apply a "balanced" load (uniform across the whole roof) and two "unbalanced" load cases (higher drift loads on each side of the ridge). All 3 of these cases should be considered separately, but there is currently no way to use more than one load pattern for design.

Designing for the uniform pattern is under-conservative. Applying the unbalanced load case to both sides of the ridge at the same time would be accurate for the roof beams, but is overly conservative for the girder at the ridge and the columns. The only work around at this point seems to be creating separate models with different loading and then enveloping the results, which is pretty inefficient.
