I would like to suggest an enhancement to the "Find / Replace in Files" dialog box. When you press the right arrow button next to the "Look in:" field, you get a list of choices like "Workspace", "Current Project", "Current Buffer Directory", etc.
I would like to see an another choice added: "Current Directory" (or "Open Directory"). This would be the directory that is currently open (displayed) in the "Open" tab. Currently, you have to either enter the directory name or else open one of the files and select "Current Buffer Directory".
This would be a very useful enhancement and improve its usability.
