In the version 0.98, you could switch pages using a single press of the key (at least in best fit mode).
In the the version 0.99, since you can zoom regardless of the mode, you now need to press the key down a few times to switch pages. Since my keyboard doesn't have single press "page down" key, it really became annoying to do it. I understand this would be solved if the shortkeys could be changed as requested in another feature request, but what I thought was that the page could simply change after pressing down at the end of a page.
Yeah, I was vaguely aware of this issue, but since I mainly use Space for scrolling, it didn't really occur to me that this would be a problem. I added a small change that avoids having to scroll more than once if the currently viewed page cannot be scrolled at all (e.g. in best fit mode or fit to height mode).
Thanks!
