Global Wireframe or Draft mode
Summary
It would be great to have an option somewhere to switch an entire comp or scene into a draft or wireframe mode. This would turn off all shaders and filters, and possibly lower the resolution to 1/4 or so, to make rendering faster.
Context
Using shaders really bogs down rendering and makes Cavalry stutter. For many tasks, turning off textures and other visual features isn't a big deal during authoring, but it's tedious and error-prone to then turn them all back on when rendering.
Examples
I don't know if I have good examples. Motion has a rather infuriating way of reducing complexity that can unpredictably turn off items and lead to confusion. AE mainly reduces output resolution, I believe. I'd rather have explicit control over this to choose between fidelity and performance myself.
