Hi Sander,

when I tell the system to open the file, a so called recognizer is 
called, which will either switch to the current document if the app is 
already open or start the app automatically if it is not yet started. So 
no matter what state it is in, it always works without any extra 
code(the magic is inside the recognizer, which handles a specific file type)

exactly, if it does crash, it is simply started the next time again

well, it is a mature and well designed software, so I don't really 
expect it to crash often :-) But you maybe don't want it at all, that's 
why I made it configurable.

It is derived from Backend, so isn't Backend.can_process exactly doing this?
