[General Questions and Answers] jttraverse:
I would really like to find a great ePub reader app and wondered if anyone here might know of one I haven't found, or have the skills to build one that will beat all the competition by including what I'll explain below.

As an author, I am very conscious of how books will look when read using different eReaders and different reader apps (FBReader, Aldiko, Laputa, etc.). There are two major issues I see so far with how the current stock of apps display the text content, and how they display images inside ebooks. Other than the iPad, I haven't found a single Android app that does both in a way that works for me (and I'm not sure even the iPad does it perfectly yet).

On text/content handling-- it boils down to whether the app actually uses the internal style that the author or publisher designed, meaning, does it read and use the .css stylesheet correctly or does it ignore it for the most part. In my case, the book looks perfect in ADE and Calibre on my laptop, meaning it displays exactly as it should look based on xhtml and the internal stylesheet. It also looks perfect on Aldiko both on my EVO and my rooted Nook color. But other than Aldiko, I have not seen one other app that correctly displays the book based on the styles and formatting stipulated in the .css file. Maybe the developers didn't think it mattered, or didn't know how to do it, but the .css file is part of the ePub standard.

As for image display--the iPad allows a double-tap to pop the picture off the page and view it enlarged (though I don't think you can pinch-to-zoom even then). The other day I was told the the latest version of FBReader for Android now lets you 'long-press' on a picture to optionally see a full-screen version of it in their image viewer (also excellent, though you still can't pinch-to-zoom on that larger image either). No other reader app I've found--even Aldiko--has the tap or press functionality to see a larger version of an embedded picture. So far I've had to do hyperlinks from the text to a larger version, or have thumbnails in the text linked to the larger picture, though still no pinch-to-zoom.

(Fwiw, the zoom function is a capability of the hardware apparently. On my EVO the internal viewer allows that--but the ES Image Viewer does not..so maybe it has to be built into the app. Pictures on an ePub book page are apparently limited by the page size unless you can view them separately, but getting them displayed with a viewer that also allows pinch-to-zoom hasn't been done yet I guess.)

So, not to drag this out any further, does anyone know of an existing reader app, or a new one under development, that has it all? I'd even donate some money if someone here wanted to look into making a reader app that combines the Aldiko stylesheet capability with the FBReader 'long-press' image view capability.

Personally, I have illustrations and pictures that need to be seen full-screen (better yet, zoomed to see the detail) so the image handling issue is a huge deal for me. The text handling using the .css stylesheet is for reading esthetics so that indentation, quotes, text and paragraph alignment and spacing, look good, as they would in a typical book--not all jammed together in the same size with no differentiation from one section to the next.

Any help, information, or ideas, will be appreciated. Thanks.
