Suggestion : search and replace in open files

I wonder if it would be possible to add an option for Search and Replace :
S & R in "open files only"

I often run S&R with the option "Selected files" only.
So I carefully make my selection in the left panel, do my stuff... and it happens I have to see something in a specific file. So I need to open it... therefore I loose my selection.

(And sometimes it's just an unintentional click in the left panel, and again my selection disappears.)

Instead, if it was possible to open the files, say to the editor to target all these open files only ?

Thanks.
