I just fooled with downloading the source of the page and stripping out elements I didn’t need.
At the very least I got a (very ugly) searchable page. With some parsing this could work until glowforge finally does something about it.
Just load up your projects, view all, scroll to the bottom, let everything load. Then, save the page (in chrome) as a “webpage, complete”, and then save it somewhere. Doubleclick on that version and you have a snapshot that will open in your browser and look like hot garbage… but at least control-F works.
It’s a really dumb workaround. I’ve been complaining about the scroll to load javascriptiness of it all for a while now, they just don’t seem to be changing it anytime soon.
Beyond that, it wouldn’t be hard to parse the resulting saved HTML to make a custom bookmark file, which is essentially a very stripped down html page anyway.
But 
none of this should be necessary. User experience has languished for too long.
