If you have a front panel object already on your cut/paste clipboard, you know how you can select another control/indicator on your front panel and press Ctrl-V and replace the existing object with the object from the clipboard? I'd really like to be able to do this with subVI's on the block diagram.

Exchange one subVI for another with a simple Ctrl-V.

I'd be OK if, when this was initially implemented, the original and replacement subVIs had to have the same connector pane layouts. But eventually it would be nice if some intelligence could be built into the operation so it could deal with minor differences.

It would sure beat delete/paste/rewire or right-click/replace/Select a VI/(find where-the-heck you filed it)/Open (although this second method could be made slightly less onerous if there were a way to REPEAT it a second/third/... time with something like MS Word's Ctrl-Y key function!)

A huge second to this request. What a pain.... I can't remember how many times I've had that problem. Always always a pain in the neck.

And the same thing for structures on the diagram, like Sequence, Case, and Formula node.
