Marco Giorgini updated his !Reader to version 0.83. It can read txt,rtf and a few more.

Reader v0.83 differences– Recent files list (that runs at start-up if it exists) to go back to the last (till) 12 opened files in the same position in which user closed them- added basic htm support (now it opens (ANSI) txt/rtf/htm and AportisDoc- added color support (for RTF only)- browse for next/previous pagebreak (in RTF files)- all support files (cfg and mrf) are in a folder called !reader under gpmm (for a quicker and easier delete of the program)- bug fixing (someone experienced random crashes – and now this thing should be over)
