For pure text files it might be possible to break a line if a word crosses a limit, but it isn't as useful as it sounds, what about a paragraph where you add a word to a line in the middle and make the line too long? Then the next line has only one word on it, yuk :-)
I agree.
Trying to do a reflow of the paragraph in real time is a problem because of the overhead and the display movements it can cause.
I could imagine of a plugin doing this.
It would be good if it is possible without display jump.
I find that just pressing Ctrl-J now and again handles most cases.
I agree. Also there is the option Line break on documents menu you could activate.
Oops, that was what I was describing as having the first problem above, but I completely forgot to mention that it already existed :-)
