Now that the design history is a feature, it would be awesome to be able to select previously done features in the design history to be able to use them as bases for pattern or mirror operations.
For example, instead of having to select all the faces that are related to an extrusion and chamfer operation, you just select the two features from the history and can continue to work on them.
I feel this would just simplify workflow quite a bit because you have a much easier “mass selection” of faces without potentially accidentally misclicking with the Apple Pencil and having to re-select a bunch of things (this could also be because I’m relatively new to the iPad but still worth considering as a workflow improvement) and overall it would make things a lot faster to select if there’s a lot of faces created as a result of few operations.
