For me it is less about the format and more about the ecosystem.

With no way to make a backup I'm reliant on them being always on and still around 10+ years later if and when I want to read it again.

But, the format also leaves much to be desired. The superbooks' "features" seem more like limitations. I cannot adjust text font or size, which is a feature! Something I've been able to do with every other ereader. I've also run into instances where the preview has text cut off even at 100% zoom. https://i.imgur.com/z8OldNU.png

Which [device, os and browser] are you on?

These books are hosted using a service-worker, and will work even if our service goes offline for sometime or your device disconnects from the Internet.

Above is latest Chrome on osx.

Chrome/OSX should work normally. I'm sorry about this. :-(

Can we look into the errors on your browser's console?

> zoom

Quick note: As a real reader will you prefer to pinchzoom on every page of the book or scale the book just once from the settings panel and be good to go?

> scroll

Scrolling is a no-go for books. My cofounder has written about this at length here: https://bubblin.io/concerns

We are aware about an issue that prevents us from using pinch features to scale content correctly on iOS Safari. The bug is raised with Apple for this and I'm hoping they'll catch up on it soon. :-)

Nah, I meant when I got that view with safari there wasn't anything I could do to actually read the text. I was stuck with that view for all the pages. With Chrome I can scroll around to read even with the off-view.
