It looks that Project for the web would adjust start/finish date automatically if conflict. It would be great in some cases, but sometimes need to allow scheduling conflict when a start-to-finish dependency task would start in the same date of the preceding task finish date. It could be easily encountered if projects on a tight schedule. It would be great to have an option to allow conflict or to have a function to fix a date of key milestones even though scheduling conflict occurs after inputting dependencies. Thank you for your consideration.
