It sounds interesting but how should the indentation scripts work then? 
Maybe there is a cool solution, but I don't see it yet :)

Wasn't someone going to submit a patch to show the encoding?
Besides that, it would already work quite well if configuring the status bar 
would work directly with a context menu on the status bar. The context menu
could simply have entries to show/hide predefined entries.
