[Feature Request] Make closing the window after copying to clipboard toggleable

[CrudeWax]

Feature Description

Self-explanatory, there are some situations in which I want to still be able to continue to work on a given flameshot screenshot and make changes in the editor without locking myself out of it by pinning the image or copying to clipboard, thereby closing the window.

Please add a toggle in the GUI to be able to NOT exit the editor/window once the screenshot is copied to clipboard!
