A malleable VI on a block diagram can be converted from an Instance VI to a Standard VI, which I've found useful to aid debugging. Unfortunately this modifies the calling code and requires the changes to be reverted to restore the original malleable VI.
This idea is to provide an additional right-click option for malleable VIs - View Instance VI. This would open the instance VI in memory, and allow read-only viewing of the block diagram.
This is useful when examining how the Type Specialization Structure cases are being evaluated given the currently wired inputs to a malleable VI. It also offers ability to quickly view the instance VI data types, helping determine which malleable input wires are *actually* broken. In the example below LabVIEW shows all of the inputs to Stall Data Flow.vim as broken, though viewing the instance VI shows only one input is actually broken.
When the Instance VI is opened for viewing, it wouldn't offer any runtime debugging, but means no changes need to be made to the calling VI when performing static code analysis at edit time.
The ability to view instance VIs already exists in LabVIEW through VI scripting (see example below), but would be nicer to have quick access to it when right-clicking a malleable VI.
