Haali Reader

The best reading program for my needs was the Haali Reader.

Highlights:

• Most important:
• Can turn screen sideways
• Automatically bookmarks 64 last books by default, you can set it up to bookmark even more books.
• Can read russian text
• English-Russian dictionary is available (maybe other dictionaries too?) It's possible to create a dictionary yourself from a text file - it simply loads the dictionary file, and searches for the word to be on left side, at the beginning of a line. Lookup is very simple: you just need to tap any word once.
• It can automatically format text to make it more readable (i.e. if paragraph is split with line end characters)
• Auto-open zip archives
• Less important:
• Change font size, color, bg color
• Bookmarks
• It's ossible to change button functions
• It can do fullscreen
• Easy to access recent files
• Automatically creates a list of contents, usually by chapters. Usually works very well
• Can search and put notes in text (in fact, you create a bookmark and you may make it either a plain bookmark or your own note)
• Auto hyphenation in russian text
• Supposed to be able to autoscroll but I couldn't find this option in buttons set up screen
• XML books

The only shortcoming is that it can't read html files, otherwise the interface is very usable and comfortable, and it has all the features I need; and some that I might need sometime.

Note: in order for dictionary lookup to work, you need to uncheck 'Use SlovoEd' in general preferences.
