Thank you for the reply! If I may add one other suggestion to optimization, a problem I find while using Watchtower is that I'll make a new subfolder in a folder watched by Watchtower, and Watchtower will briefly add a folder named "New Folder" before the operating system renames it.
For example, I'll be working in a folder called "Broll" and I'll make a new folder for "Camera B" and Watchtower will add a "New Folder" folder then a "Camera B" folder and "New Folder" will raise the offline-files dialog in Premiere because it has been renamed.
Perhaps a solution would be to add both "\Proxies\" and "\New Folder\" to the filter list by default?
Thanks again for Watchtower, it's truly great.
