I just signed up for the basic plan in order to test BookFusion more.
Apart from my previous recommendations:
- Option to disable animations
- Option to use both sides for tap to next page
- Vertical slide for brightness control
Here's another:
- Larger side tap zones for page turns
In general, switching pages is the most used function while reading. With BookFusion on my iPad mini 6, the side tap zones are way too small so I often end up opening the menu when I want to go to the next page.
On my Kobo e-ink, I think the screen is divided into thirds which I think is a reasonable default.
