It would be nice to have user actions attached to given file. I mean to attach them not only via filetype and wildcard but also on similar basis as you attach emblems to items.

F.e. I have /srv/home/konrad/trash directory (I use libtrash). I wanted to attach an action (Empty - "rm -rf $HOME/trash/*") only to this directory. I've tried to use "/srv/home/konrad/trash" as filename and only for directories but it didn't work.

This way you could attach a lot of usefull actions to directories like (examples):

/srv/www/project/www.foo.org - Sync with server - script to upload files via FTP
$HOME/dev/project-bar - SVN checkout - script to checkout this project with server

Etc.
