Apologies if this has already been posted, I've search for as many phrases as I can think of in the forums ("Change Folder", "File Location", "Route Directory" etc), but couldn't find any mention:

Is there any way to change the default location for storing and opening Flight Plans with PC SD Plan?

Currently routes are stored in C:\Users\{MyUserName}\Documents\SkyDemon\Routes, but in order to have the routes available on all my various home/work PC/laptops/phones I'd like to be able to store them within my Google Drive so e.g. C:\Users\{MyUserName}\GoogleDrive\SkyDemon\Routes. I can store the files in that location and load them from there fine, but every time I click to open I have to navigate from C:\Users\{MyUserName}\Documents\SkyDemon\Routes to C:\Users\{MyUserName}\GoogleDrive\SkyDemon\Routes every time - even having opened a route from the new location, SD doesn't remember it for the next load let alone the next time it runs.

I've tried looking in the program preferences, for a config file on the disk and even in the registry, but no luck. I'm hoping someone can point out a way for me - perhaps there's a secret command line option that can be used when starting SD?

I have exactly the same setup, during installation of Windows 7 I told it to put all the 'Users' stuff on drive D (a traditional spinning drive) rather than drive C (the SSD).

Come on Tim, this is a very basic request for the program to simply remember what directory the route was last saved to/loaded from. It's standard fare in most programs. If just done by remembering last folder there's not even a requirement to have a "setup" parameter for it. There's nothing to "support" about it.
