change the behaviour of Recent when saving a file
In the "Choose File System" menu that appears when opening or saving a file, the "Recent" option displays a list of recently-opened files. This is fairly useful when opening a file, but when saving a file it's only useful on the very rare occasion of wanting to overwrite an existing file that has been opened recently.
A more useful behaviour might be to offer a list of folders that have been interacted with recently (e.g. take the list of files that have been opened recently, and list the folders those files are in), and selecting one opens the usual file system window to let the user save the file in that folder.
