Hello, I would like Synfig Studio to have a wire view or a contour view in the work area. Only the contours of all types of layers are visible in this mode. I think this could give a light and useful viewing option when it comes to making animations.
I hope it is useful.
Thank you.

For inspiration to developers that wants to tackle this please take a look at how professional software does it, such as:

Ideally I think this proposal could have added some important details:
I also think each geometry layer should have a color tint specifically meant to be sued with this "wireframe" mode, that way it's easier to distinguish visual groups on the canvas, instead of everything being colored black.
We should also have an option to isolate the participation of a drawing layer on this rendering type, but this is true as well for all rendering types. Sometimes the animators want to see everything as a wire, except the current prop or character they are working on. It should be considered to also add a base feature that allows other rendering types to be filtered, so if I want some elements to be of draft quality, and others to be of wireframe quality the animator can quickly change between these.
If I think of anything else I'll edit this comment to avoid cluttering this proposal.
@Jose-Moreno This is a good start!
Since this feature needs a well-thought and detailed description, I suggest to create a special page in Developer Documentation - https://synfig-docs-dev.readthedocs.io/en/latest/ (we can add a special section for projects like that).
This way, the proposal can be enhanced by several users, while discussion can be continued here. ^__^
