Is your feature request related to a problem? Please describe.
Those who use KDE Plasma and Spectacle or Flameshot may be used to having the option to simply drag and drop the image through the notification. This is very useful as you don't even need to open the program interface, just use the shortcut, capture the image and then it is as a notification in the corner of the screen ready to be used.

In addition, you will be able to use an action menu based on the file type and use native system integrations such as KDE Connect.
