I'm not sure if this is a request, or something that can be accomplished now.
I use an app called Default Folder X and one feature I use a lot is whenever I have an open/save dialog box, it allows you to click on another Finder window and that window/folder is then transferred to the open/save dialogue box in whatever app you're using.
It saves a lot of time navigating. I know you can drag a folder from the Finder onto the open/save dialog box and it will open that, I just prefer the method that Default Folder X uses (it's also much faster) and I wondered if it were possible to achieve that with BTT or something that could be added?
