Suggestion: Option to remember previously downloaded galleries/images, even after completed tasks are removed

[inger147]

After downloads are completed successfully, I tend to remove them from the list view so it doesn't become too cluttered (I use the "Remove automatically after complete download" option in the Advanced options). I also sometimes move or delete galleries or images I've downloaded previously (typically because they are duplicates, or I watched them already, etc), but if I do that, the next time I do a batch download from the downloader to acquire new galleries/images, all of the images I previously moved or deleted will get downloaded again if the links for those are included in my batch.

Can there be an option to remember all URLs that were previously downloaded, even if they are removed from the download list? It would be very helpful if a similar prompt could appear as if it were still in the list, i.e. "This task has previously been completed. Do you want to download it again?"
