Preview Resolution options above the composition resolution
Importing vector assets into AE can sometimes lead to arbitrary and sometimes very low resolution precomps that you have to animate within unless you want to go to the effort of resizing things in both precomp and master compositions. This resizing doesnt do anything objectively since its all vectors, it'l all shake out fine in the end.
But during the production it is a pain to either animate in very low resolution compositions or to go to the effort to resize things.
The option to just set the preview resolution above the compositions actual resolution, in the same way you can make it preview at a lower resolution, would solve this.
