The 'ordered set' seems to follow different rules than the
ordering of ports in the main display. A similar thing
happens if you select two apps expecting that connections
will be made in the order they are displayed - usually
it's different.

Whatever the model, I assume it can represent an arbitrary set of
connections. If not it's a wrong model. If it can, why doesn't
that happen when you make a snapshot ? What is the purpose of
making *other* connections ?

A collection of useless files that have to be deleted.
I like to keep my home dir clean (the junk yards are at
deeper levels). If you could at least save to an existing
file the pile wouldn't grow so fast. Imagine that emacs
wouldn't allow you overwrite a file...

As far as I can see there is no technical reason why a 
patchbay should saved before it can be active. Nor is
there any good reason to impose this rule.

I have three:

1. Snapshot = exact copy of existing connections.
2. 'Current' patchbay exists without being saved.
3. Allow overwriting files.

I imagine that 2+3 would actually simplify the code.
