I just wanted to post a bit of information that may be interesting to many iOS users here in case this hasn't been noticed before.
Apple has a community forum dedicated to accessibility and one of the forums is focused on vision.
The link is posted at the end, but I'll just point out why as a blind user you should checkout this forum:
1. It's more than likely that folks at Apple (all departments) monitor those forums, so bugs and feature requests highlighted there may have some positive effect.
2. It looks like low vision and newly and/ or cutoff blind users post there, so those interested can help out by answering questions.
3. Developers are also likely to quickly scan through those forums.
