"Show differences" warns about, more than one pair

[Alibert]

When selecting more than one file "Show differences" warns about more than one pair of files selected and asked if i want to continue.

Please add this to "don't ask/tell me again" messages, so we can turn off this prompt and always start the comparison program immediately with the selected files.

I frequently select more than one pair of source files to compare them in "Beyond Compare" or other file comparison programs.

I also support the addition of a shortcut to call "Show differences".
Hope you consider my proposal.

Greetings, Harry
