I want to click on Save and automatically save photos to specified folder. Thanks.
You can do that with -p or --path, as in: flameshot gui -p ~/Downloads
I use this icon to create screenshots. How can I put this flameshot gui -p ~/Downloads there?

It seems that isn't possible yet. The issue was previously raised in #207.

Hi @renat2985!
I have resolved it not by clicking on the icon but with a keyboard shortcut, that is also really fast and handy.
Just assign the command flameshot gui -p ~/Pictures/Screenshots/ as a keyboard shortcut for the _prntscr_ key. Replace the folder for whichever directory you want and that's it :smiley:
And don't forget to click on the "Save" icon, if you press enter the screenshot will be only copied on your clipboard!
Many thanks to @tastytea :wink:
Thank you @call0fcode it helped me to get rid of all the pain with screenshots!
In addition, at least on Ubuntu 18.04 it expects the path to be absolute so ~/Pictures/Screenshots/ should be /home/youruser/Pictures/Screenshots/
