We have a CMIS interface to our database and are using it with Adobe Drive 4. The Bridge does not show thumbnails for the assets in the database. I have tried connecting to a different CMIS repository (Alfresco's) and thumbnails are not shown there either.
Can the bridge show thumbnails of assets accessed via the CMIS connector? If not could it be enhanced to do so? We support the cmis:thumbnail rendition (and a few others) that could be used.
