I'd love an IntelliJ IDEA plugin where you could submit a local changelist (group of files within a project) to Code Collaborator.

Currently (at least when using SVN) when a file is renamed, the original file shows up as deleted and the new file shows up as new. The problem is that all of the bugs and comments stay with the original file (now deleted)

Users want to comment on a block of code, not just an individual line of code.

A checklist to keep track of / remind reviewers ensure the author's code is not only functionally correct but satisfies the companies coding / checkin policy. Also would be a good way to prevent recurring bugs / issues by having a way to remind reviews to check for them.

code collaborator should allow deletion of file from review, if uploaded in error by author.
Currently, author has to delete review ad recreate new review.

Please add an ability to specify additional syntax / highlight rules, for languages without builtin support. In my favorite editors, I can create a file that tells it how to highlight a new language. It would be even better if it supports an existing format for the rules (I use SlickEdit and PSPad).

Reviews are less effective when the execution path can not be readily followed across files (including those not changed), and symbols cannot be located. This is a serious defficiency in my opinion, leading me to jump over to an editor that supports this, and then back to the review.

Many companies could benefit from Code Collaborator being Part 11 Comliant. The tool is mostly compliant when LDAP is used. This is the only feature that would need to be added. It doesn't seem too time consuming and you can gain a lot of customers in the highly regulated industries.

Define any number of "pools" of reviewers, where a pool is made up of any number of users.

You can then assign reviews to a pool. Email/RSS gets sent to the members of the pool so they all have a chance to "take" the review.

On the review screen there is a "Take It!" button so it's easy for one person to claim the review.

Would be great to be able to set a default of "roll up all changelists"

Customer would like to be able to say let people view this review who are either in the group associated with the review, OR a participant of the group.
Users should be able to invite participants to a review who are not in the group as part of this feature.
Just selecting "Participants" is not a valid workaround, because that keeps other members of the group from being able to view this review.

It's useful to know when people commented, or how much time since the last comment.

This would be particularly useful in larger reviews where each reviewer is only responsible for a small portion of the code under review.

It would be great if Delphi source code (.pas files) had syntax colouring in the Diff Viewer like other languages do already.

If native support isn't possible, some kind of mechanism to create / add syntax colouring ourselves would be just as good.

Others have requested ability to display p4 jobs (most often defect tickets) associated with a changelist. That's great. It would be just as good (if not better) to also create P4 jobs for every review in the system so when we submit changelists we can natively select which review it may be associated with. Without having the user to enter some regex matchable string into the comments.

Like you have for Perforce and Subversion now, but for TFS.
