I would be nice to have spectacle remember coordinates of the previous rectangular snapshot. This allows to take multiple snapshots easily and keeping exact same image coordinates and size. This featured existed in ksnapshot (see bug #233404) and it would be nice to have it as well in spectacle. Reproducible: Always
This has been in Spectacle since KDE Applications 16.04
I'm glad to hear it has been added, I'm sorry I hadn't noticed the checkbox. (If you allow one off-topic comment, it's not obvious for the new user that a button "Save and Exit" will offer a Preference menu.) Thanks for the code!
