There are numerous ePub file readers on Android and I tried several before deciding on one to use for good. Now I bought “The Emotion Thesaurus” which is a reference book I’ll use at my desk, not a reading book. So, I want to open it on my desktop PC. I’ve searched for ebook readers, and the findings were terrible! First, I want something that can simply open a file, and strongly prefer that it can easily be configured to run when I double-click an *.epub file in a file explorer window. So, a program that requires files to be ‘added’ to its own internal library first, as a separate step, is a non-starter. Likewise, programs that only look for book files in specific configured directories! And if it does need to show a File|Open dialog box, please use the standard system one rather than a ‘pretty’ but half-baked one. Hanging forever when I navigate to a directory is simply not acceptable. Requiring click-by-click navigation (no place to paste a full string) when I already know the complete path of the file is very rude. But, as I noted, I generally shouldn’t need the File|Open menu item, as it should be integrated with the Explorer (e.g. take a file as a command-line argument and have the installer register this as a handler for that file type) and be a drop target. And when a file is opened successfully, it should display the contents in a sensible way (why do I even have to say that?!) as the epub book is intended to appear. It must have persistent bookmarks and a Search feature. It must allow copying text to the clipboard (even if it spans a page break). Nice-to-have would be margin and text size configuration, etc. Anyone know of anything?
