Feature request / Bug report?

Hey! So, vector guided tweening is a bit broken when Draw Under is enabled. It would be great for vector fills to reference other layers, in which case I wouldn't care about the bug and this would be MUCH more ideal than draw under not changing the order in which stroked are recorded.

The issue is that I think draw under is changing the order so that the lines drawn are recorded first. This makes it so that the previous lines are "drawn last" and thus on top. I think a Z-Index based recording of lines would be more sensible.

Thank you for providing the video link. Excellent illustration of the issue you're describing.

Would simply having the arrow-indicators (redraw order) reversed in situations where the "draw under" option had been used serve to accomplish the necessary fix (i.e., rather than having to remember the original drawing order and ignore the arrow-indicator suggestions)?

That would be pretty fair solution, yeah. I think that would probably be a very involved task though because the "layer" order of a stroke is tied to the sequential stroke order. Even when you select a stroke with the select tool and choose Move Forward or Move Back, the sequential order is also tampered with. Having column reference fills would be the better solution, to be honest, and would fit with most artists workflows. I dunno, just pitchin' ideas here.
