Right now each directory is named something akin of “Download Directory #1” followed by the directory path after that.
However, I can imagine that for a lot of people that it might be confusing for which plane model that directory could be, e.g. for pmdg that has a fairly big line up of planes and is still growing.
My suggestion is the ability to add a name or tag to each download directory in the SimBrief Downloader, e.g “Download Directory #1” could be named to “737-700”. This may be something thing fairly minor but for the sake of clarity could make the use of simbrief downloader a bit more streamlined
