Description

Because we all have very different needs, and I guess that you don't want Mousepad to be bloated with too specific options, it would be good to have an option to pipe the text to an external command or script. This way the experienced users could extend the functionality of the editor (up to some point) without the need to request new features every time.

For example, one could pipe the text to the command "sort" and have all lines ordered.

I don't know how complicated it would be to program something like this, specially because of the possibility to undo the operation. But on a first stage it could be a irreversible operation, warning the user before, of course.
