The new Set Revision feature in SOLIDWORKS PDM is awesome! I love it. We've been waiting for something like this for a while.

However, I would request that one of the column headings in the dialog be updated. The column that says "Next Revision" I think should be updated to say something like "New Revision". The reason is that it is very easy to confuse "Next Revision" with the SQL database entry for "Next Revision" that gets referenced by the Set Variable action in the workflow (i.e. %nextrevision%) when the Set Revision function is actually updating the current revision value to the value selected under "Next Revision" and updating the %nextrevision% value accordingly. This could also be confusing if a user is attempting to go back a revision, for example, setting the "Next Revision" value to D when the existing value is E.

I believe that updating "Next Revision" to "New Revision" or "Update Revision to" or something similar would eliminate confusion between the two terms (Next Revision pertaining to the Set Revision Dialog, and Next Revision in reference to the SQL table entry).
