Hello! Nice work here and thanks for pinging me!
Downloaded the new build and tested it. Seems to be working well. Thank you so much for doing this.
My only other comments would be regarding design, it would be cool, when you guys get the chance, to more align your UI with the media library overlay controls. They are a bit small in terms of ability to click / focus, and also the arrows are not quite matching. Wonder if you could even utilize the same controls pattern WP does or if that would be confusing, either way, just some thoughts:
Ignore me if this is an early build and you plan to hit that stuff before releasing.
Thanks again!
