Minor bit of feedback: the camera framing part of the intro process wanted me to move so close to my phone (only a few inches from my face) that I could no longer comfortably read the screen. Perhaps I have a small head.
I work at AttendZen -- our product is built using Svelte, but our marketing website (currently) isn't. I'll investigate to see what may have caused a slowdown here, but it's definitely not down to Svelte.
I'm in exactly the same boat. It's such a shame that AFAIK nothing can import .fw.png files and keep them editable; I'll need to manually export everything to .psd before I eventually have to upgrade my OS.
