Figma Slides reduce my powerpoint frustrations tremendously, but they come with a few usability challenges. The slides have a general center-align and align-with-item snap to them, but getting better auto-layouts and more sophisticated templates would be a huge asset. Clear UI to create or save templates would be great, as well as live color changes to-template. If I change all of the colors in a template, having to go through my slides and reselect my template colors is redundant. Overall I would love to use Figma slides more than I am able to.

A huge request is finding a strong integration between Figma Slides and Figma wireframes or Prototypes. Jumping straight from slide into prototype, or being able to have a natively stretched-to-fit wireframe in my presentation would immediately create adherence to Figma Slides over Google/Microsoft variants.
