Hi! In Cinnamon's file manager Nemo it is possible to integrate meld in such a way that when nemo shows the warning dialogue that would overwrite a text file, I could directly browse the diffs between both versions. This is very handy!

I now switched to KDE & Dolphin (as many things are really more advanced and provide a better usage experience for me), but I miss this feature.

Is this possible somehow (with any diff tool)?
If not, is there a hook in Dolphin where an extension could link into the file overwrite warning dialogue?
