Adding multicolumn text is on my to-do list,
I'd much rather see what others have suggested... column copying. In other words, rather than copying text horizontally only (if you move the mouse down one line, you get everything horizontally from the starting point, onto the next line up to the ending point).
This is a long line of test with multiple lines and the color
is what is copied if I start
the copy at with and move down
one line without moving horizontally.
With columny highlighting, I can choose to do something like this (move down 1 line and horizontally about 10 spaces):
This is another long line of text with
multiple lines and the
color is what is copied if you move d
own 1 line and horizontally
about 10 characters (including spaces)).
