Re: Nautilus "open with other application" doesn't allow other applications?

Hi. Do you plan to 0) make a "desktop" file editor or 1) store MIME 
associations added via Nautilus in a custom database internal to 
Nautilus? If 0, I guess that the editor is beyond the scope of Nautilus 
(and beyond the scope of just "fixing a bug" :) ).
