Great but needs a tad bit more Rated 4 out of 5 stars
I think "save file to" needs a function to add,at any time, a new folder on the fly. Say you select and want to save an image,you want it on the desktop in its own new folder: you need to minimize firefox,make that folder and only then can you use "save file to" to add it to that folder.
This would make "save file to even more convenient then it is now.
Another feature that would be awesome is when in the context menu ,you are traveling through the folders,you can on the spot decide you want to add that folder to the stock folders that you always have for that particular file type. Right now you need to add it by going to the option and add it there. While this is fine,it doesn't make for a very flexible experience.
You could implement this by showing Icons next to the folders,in the context menu,and if you click the icon,that folder gets added to the quick search. If you already have that folder added, clicking it again would then remove it from the quick searches.
These 2 options would take this wonderful addon to the next level.
