[feature] Option to change the behaviour of 'Diff' to not open new window

[oliroe]

Version and OS Docker 0.39.9

Is your feature request related to a problem? Please describe. Not a problem as such, the 'Diff' button currently opens a new window and I'd like an option to open it in the current window

Describe the use-case and give concrete real-world examples Checking lots of differences currently opens many windows

Thanks
