For some websites, downloaded images have no file extension which makes them unreadable by any normal picture viewer. I tested this on unsplash.com. Most other websites seem to work fine.

Changing the folder names in the settings doesn't work so I'm stuck with the default ones. I tried clearing the folder name settings so I could get a one-click save button instead of the normal *save as* option, but that doesn't work either.

Downloading files with identical names are automatically renamed to ...(1), ...(2) etc, which I really like.
