Buying ebooks this way avoids giving money to A***e or A****n, and with a contribution going to your local bookshop. So far, so good. It is still a proprietary system like the others, and you are at the mercy of what the developers do. So far, main gripes are: it doesn’t play nicely with windowing, often resizing wrongly and sometimes the Options panel disappears before you can select from it; it lacks a lookup function; it doesn’t respond to external keyboards, even the arrow keys; and its layout is ugly, with a ridiculously excessive gutter margin. I’m sure it will get better, but it needs to do so fast to avoid being written off as a very poor substitute for the established reader apps.
Thank you for your feedback and for helping us support independent bookshops. We're sorry to hear about the frustrations you're encountering using the app. We take this feedback seriously and are diligently working to improve the experience with each new app release. The good news is you should already be able to search within a book by clicking on the center of the page you're reading, and upon the "pill" menu displaying, click on the ellipses (...) to pull up additional options, one of which is "Search book." Currently, our ebook app is much more mature than our web reader, and some of the challenges you're encountering might be tied to using the web reader on a tablet/device. If that's the case, we'd recommend downloading the app in lieu of the web reader. We would also be happy for you to email us at product@bookshop.org so we can help you troubleshoot further!
