I think ReadThemAll is a nice text-reader application.
Who knows you find it useful to include it as part of portable apps.
Description: a hand-free text-reader, several auto-scroll options, font and background color options, Rotation, Bookmarks, Searching, Hyphenation, Portability (doesn't need installation, runs from any place)
1. The application (RTA.exe, 969kb), after running once, will create "RTA.ini" and "rta_qpos.ini" in the same folder where it is placed.
2. If a text file "abcd.txt" is opened, a file "abcd.txt.rtainfo" is created in the same folder.
