Hello to everyone,
here is one more idea, which I'd like to propose.
As for me, it would be useful to have the following: when all components (functions, wires, subVIs, etc.) are selected on the block diagram (like, after ctrl+A), operator could do right-click, and in the menu would appear menu item "Disable everything". After it, all the code could be placed into Disable structure.
Of course, I can add Disable structure to block diagram manually, and cover whatever I want, but with right-click menu it would be much faster.
Also, it can be modified to disable only selected items - then each of them can be placed into separate Disable structure, and, for example, additionaly in the enabled case of Disable structure, corresponding wires will be connected. Sometimes it is needed for testing - just to disable couple functions, and test subVI. Or to disable subVI fully (it's faster, then disable place, where it is called. Especially, if subVI is used in many places).
It will not make debugging difficult, because anyway Disabled structures are used; such functionallity can just make life a little bit easier...
Any idea that has not received any kudos within a year after posting will be automatically declined.
