Too slow/too much effort to file a bug.
The situation I was realizing I need this feature is when you are in 'the flow'. You go through implementing a new feature and you touch/change a SubVI in another 'code modules' to make your new implementation working. In this situation making the SubVI 'clean' would throw me out of 'the flow'. I want just a amazon-one-click-buy-button to mark that SubVI as dirty and go back there later, when the 'big-picture' is implemented.
But it would not be a bad idea to have an option to sync these statuses with a bug tracker like mantis (e.g. by writing the status in a data-base), as well as to have any status changes in the Changelog of my SCC (maybe as pre-commit hook).
