Hello @Keith-Shannon,
imho, that isn’t possible yet and in addition I don’t see how it can be implemented easily.
The reason for this is that the underlying scintilla component doesn’t allow to set a
predefined width.
What could be done, as long as it is text you wanna reformat and not code, is using split lines
which takes care about the vertical line but the split is always done by word boundaries.
CTRL+A and CTRL+I
will give you an idea about this.
Cheers
Claudia
