These is new version 1.03 of QT Box Editor. There are two important improvements (for me ;-) ):
settings dialog — with this you can select font (frankfurt, hieroglyph, or some other ugly and useful) and colours based on your needs…
possibility to move symbol/box within table/model — currently I work on training that is based on photographs of very old book. There is problem to make all lines of text straight (with available tools). For this reason tesseract-ocr has problem to set char/symbol in correct order e.g. I can not use box file for creating list of words.
