About a year or more ago... I could merge two files in the File Browser into one.
The trick was cool

You could kind of create a double exposure.
Sure, this is faster and easier to do in the PC, but the trick was cool.
I can't find a way to do that now.
Was this removed or is it somewhere else?
I also noticed (A590IS) that both "+/-" and "Disp." buttons now act as delete in the File Browser.
And there isn't a way to mark or select a few files... Unless I am missing something.
