[Gimp-gui] Auto-shrink checkbox

[Georgy Grigoryev]

In earlier versions of GIMP was a "auto-shrink checkbox". Than it was
replaced with button, which is more clear show what is the checkbox doing.
But it works only one time. If you extract a lot of elements from frame
it's tiring you for every element click button. I mean if you have a
checkbox to enable auto-shrink for every selection it will be great. Button
shrink selection one time, and checkbox enable auto-shrink for all. What
about that idea?
