Hi - thought I would throw in our ha'pence worth on the old revisions nugget.
I thoroughly endorse the need for a dedicated field for revisions, and would extend that to requesting the ability to link layout number/name/revision fields information out to Excel to provide live drawing schedules....
In the mean time, our work around is to use the Layout Name field as the revision field. We manually insert the drawing sheet name as ordinary text on each layout - gives better control over the format and length of titles.
This has really been driven by Publisher. It truncates file names in an incredibly annoying way when exporting files, rendering a descriptive name useless, and not acknowledging the revision of the sheet/file. Using the Layout Name field as the revision field has the benefit of adding the sheet revision letter to any file exported using Publisher (we start with "-" as the default original issue). I enclose a screenshot.....all very simple, really
