Great. Yes I suggest you learn a little more about the Workflows, they are very powerful. Each workflow has its own variables. Start here: https://www.alfredapp.com/help/workflows/advanced/variables/

@noisyneil sure, all you would need to do is edit the "dest_dir" workflow variable and set it to just "Desktop":
 

Not a clue. It's exactly the same code, as far as I can tell.
 
 
Not if you also tell Finder to do the deleting. There'll be two operations on the undo stack, instead of one, but I wouldn't call that messed up. It's arguably better that way because the first undo would restore the originals from the trash, which will be a lot quicker than copying them back over from another volume.

nice to know i'm not going mad. :-)
 
...although I did get my shortcuts muddled up. they're in my muscle memory but not in my brain, apparently!
 
cmd+shift+3 = whole screen screenshot, saved to desktop
cmd+shift+4 = drag cursor to define screenshot area, saved to desktop
cmd+shift+ctrl+3 = whole screen screenshot, saved to clipboard
cmd+shift+ctrl+4 = drag cursor to define screenshot area, saved to clipboard
 
None of these work opens a 'screenshot window' and none of them work for me with the workflow. 

I just tried Webscreenshot and, bizarrely, it takes a screenshot of the desktop wallpaper, despite other screens being in front of it. Very strange, but feels like it's very close to working! 
 
EDIT: i had to give Alfred permission to record my screen and now it works! phenomenal! thankyou @vitor!!
