Okay, okay... :-)

Yep.

Mmh, you're not really proposing to provide an API for each 
partitioning scheme and file system, are you? I would consider that a 
bit of overkill. In my opinion the GUI add-on is sufficient and 
preferred by 99.99 % of the users. If someone doesn't like it, or has 
plans like mass-partitioning over network, well, the sources are open.

BTW, for the intel partition module, I extracted the reusable code into 
separate source files (intel_partition_map.{h,cpp} for the structures 
and intel_parameters.{h,cpp} for the conversion to and from parameters 
strings), that I intend to reuse in the GUI add-on. I would see 
nothing, that would prevent anyone from using them as well.

Yes, that could be done. Though, maybe the FS add-ons are the ones to 
be asked.

I somehow doubt, that this will happen. Not that I wouldn't find that 
desirable.

Yes, we will see.
