gnome-screenshot doesn't autosave but interactively asks for a save directory

I've specified an auto-save-directory in dconf-editor under org.gnome.gnome-screenshot however it still asks me for a save directory every time I take a screenshot. ---------- In prior Linux Mint versions (17, 17.3, ...) it went like this: I press Print, the screen goes white, and then I continue doing what I was doing (with a screenshot being made and put into the auto-save-directory) In 18 however a dialog pops up after it goes white and asks me interactively what I want to name the screenshot and what folder I want to put it in. I find this very annoying since I put them all in the same folder and don't bother with filenames since the current date and time are usually descriptive enough (plus they're chronologically sorted). Can I change the behavior of gnome-screenshot or are there any alternative programs?
