Would anyone know how to prevent accidental duplicate opening of the same file in Kwrite ?

Kate (which shares the same code base) seems to do this by default: If I try to open a file that is already opened in another window, it brings the window up, instead of opening the file in a new window. This seems to be the norm among most of other text editors too. In my experience, it prevents a lot of confusion and editing conflicts.

Also, thank you KDE developers - you guys rock!
