Polyline end caps
Being able to add caps to the end of Polylines would be great, obviously only applicable if it's not a self-closing polyline. This with 3D polylines and the per-point thickness would be especially helpful for creating some interesting effects.

It would be great if this was implemented separately from the big polyline rework, even if it's in a semi-incomplete state.
For example, my current Polyline uses the same width for the whole line, and it only has 3 points. It's a super simple use case, but it looks bad with flat caps, so I'll have to do something logistically awkward with two Lines instead. Adding rounded caps to Polylines would be extremely convenient, even if there are some caveats to when and how they can be used.
EDIT: I was able to solve this using Surge's SplineRenderer (I had already bought Surge a while ago). I believe the corner rounding isn't as clean as it is in Shapes, but I was able to get the rounded caps that I wanted, and it was easier than trying to line up a bunch of Lines into a pseudo-Polyline.
