Interesting idea. On a related note, one of our longer-term ideas is
to offer local text-file editing: in other words, the ability to
download the contents of a text file to TTPro, and then use a multi-
line text editor (or something like another "terminal" window?) to
allow local text editing.
But perhaps your idea is a much quicker way to accomplish nearly the
same thing. For example, you could cat a text file, copy it to the
clipboard, and then open up the multi-line editor and paste the
contents in there. Then edits are easy, as well as auto-correction,
and when finished the contents would go back to the clipboard.
Actually, after that's implemented, it seems like basic local file
editing would be pretty easy -- it would just need a few automatic
shell commands (similar to how Directory Navigation works), and that
should be it.
If we could then integrate gestures, keypads, and TT auto-completion
on top of the multi-line text field, we'd have something pretty darn
neat. :)
