i wont miss it, like i never missed it for over 2 decades now. saving as DOC but could not work with Word DOC, not playing well. there ever existed some kind of better rich text editor which was small. during century change i had ms office then changed 2004 to openoffice and some later to another one. if some reduce softmakers textmaker to the minimal files ofc some will have a nice package with ~80megs - and portable.
I actually still use it sometimes, but I was indeed surprised that it's not compatible with MS Office documents.
