I just tested in LabVIEW 2011: It is already possible to select any item in the IPS, however only once for each item! Try removing one element and look into the menu again.
EDIT: Had the feeling I missed an important point here, so I read your post a couple of times... You try to change places of one element of the Unbundle by another one right?
You cannot have the same element twice in an IPS, since the whole point is to prevent data copies... Swapping their positions however is an interesting point.
Maybe we could get a dialog where we could change the order of items similar to a case structure? -> With options to drag-and-drop or 'Order By Name'

you're right. It is indeed a difference between IPS-bundle-unbundle and the original bundle-unbundle.

very good idea !
I'm not sure I fully understand what this idea is. I think there are a couple of different interpretations...
* Just wanting to change the order of the unbundle or rebundle, to avoid crossing wires if you want to swap items.
* Wanting to actually change the cluster order.
Is it one of these? Can you clarify?
By the way, I vote no for either of these interpretations...
* I think there's benefit in not having to study how the unbundle and rebundle might be different on the left and right sides. A crossed wire is actually a good visual indicator that I'm swapping something.
* An intended trait of the IPE structure is that the data going in and going out are in place. Changing the cluster order means that the data type isn't the same any more, so it's possible that the two can't be in place.
The idea has nothing to do with cluster order, and the IPES does not care about cluster order. You can (eventually) put the elements in any order you desire. No suggestion is made to have the LHS and RHS order be different.
The issue is that reordering the elements is a bit difficult because you can not have the same element twice, you must remove one and then add it again somewhere else.
Reordering the elements would be a far better solution than this idea IMO.
(And I never understood why Unbundle By Name allowed the same element multiple times. It used to thwart recognition of the so-called "magic pattern" but I haven't checked recent versions).
I understood it the same way Darin did. The reordering he referred to could probably be done as a right click option for "Move Up" and "Move Down", which will move the terminal (with its wire and corresponding terminal on the other side) one up or one down.
Nothing wrong with allowing the same element being selectable on multiple places in the IPES data container. LV should just temporarily break the VI until the situation has been resolved (until the swap is carried out fully in this case).
The inability to (temporarily) select an element more than once has always bugged me. It is a good example of the IDE trying to be smart but only really making a simple thing difficult in the end.
