When we look on the Commit tab at all the changes which have been made to our test environment, it would be useful to be able to see if objects are still being worked on (and who by). Could we have a column next to "Last changed by" to indicate the user who has the object locked?

For example, if one of our developers is still working on a given stored procedure, they don't want me nagging them to check it in if it is a part of a larger piece of work, which will all be checked in together later in the week.

Equally, I don't want one of our other devs to commit this work to Source Control inadvertently (especially when it's been picked up as a possible dependency in someone else's work).

NB: We're using the Shared database model, if that wasn't clear from the above!
