Mario Rodriguez, a program manager on TFS version control, is seeking your input on what you need in the way of checkin policies for a future power toys release. An example might be a policy that wraps another policy to provide path filtering to more precisely control what files are subject to a particular checkin policy.
Please leave a comment on his blog post.
I have decided to skip the post about merge and deleted items for today in order to get some feedback from you on Check-in Policies. Currently, we are thinking of releasing a check-in policy pack out of band that includes some very commonly used policies, an example being "Check-in comment field cannot be empty".
