Agreed, the second path realised with preset names is what most people 
want.

With a profile containing a preset string the difference goes pretty much 
away. Just show the preset string to the user and we have the cases more 
or less merged. I imply that a embedded calibration is mandatory and 
should influence the GUI options. So switching the preset string as well 
comes at minimal cost.

To make a difference, it should be as well possibly to change the profile 
in the colour management dialog. Simply why we need a way to connect 
arbitrary calibration to a profile without calibration somewhere. We will 
for a long time see profiles which have no calibration and need one to be 
associated. The print dialog is the ideal place for that. I do not know 
where else. So we will end with following main and special tabs:

------------------------------------
<Main view>
Select Preset [Internet\/]
------------------------------------
------------------------------------


------------------------------------
------------------------------------
<Colour Management Tab>
Select Profile [myProfile-01\/]
------------------------------------

Most users will not even know that there is a colour management tab.
