Image Masks Thumbnails

[fandj]

I have generated a number of Image Masks, which I can only identify in the Production Library through their respective names. Of course I have created files for specific masks (e.g. rectangular, circular) to make it a bit easier. It would be very useful if I could visualise them promptly (i.e. without clicking on it to call the Overlay Options window like we have in Moving Paths and Video Filters. Any help please. Thanks in advance. Regards.
