I wonder if it is possible to replace the editor window for certain
filetypes. This could for instance be used to write a plugin for doing
image manipulation and editing.
I know I can add a item when right-clicking
the file and make that menuitem popup a new window (or toolwindow) where I
can put my imageeditor. However it would be nice if I could show the
instead of the default texteditor because for instance I still want to be
use the tabs for switching between files.
