In the list of iModel names within the list tree, the model descriptions are shown before the file number.
In ProjectWise, files are listed as File Name, and then File Description. This makes it easier to determine the owner/discipline/sequence of the file.
While on paper, I understand it makes more sense to have the description first - to identify the information within the model. In practice, it's actually far easier to have the file number shown first instead. Plus it makes the file number and description much easier to read.
