As I already noticed on your forum, there was an entry concerning notepad++ invocation from the command line. using notepad++ from the command line with an option file performing some tasks on a file would be a great feature.
C:\Program Files\Notepad++>"notepad++.exe" --script script.npp myCFile.c
would open the notpad++ gui and scroll the file to the line 150
I would also imagine other scripting possibilities, like convert a file to unix/windows format, and so on.
