As for downloading the saves; would it sort of be like Garry's Mod Toybox where it only uploads it once then you use it to your content, or will it add as a new save to your save menu?
If it gets added to your save menu, it would end up clogging your save folder with saves that you will only use once. I have come up with 3 possible solutions to this.
1) Make it like the Garry's Mod Toybox where you only use it once and then if you want it again, you download it again.
2) Make a save delete button in the save menu. This will not only fix this problem but many other problems players have had with clogged saves. You could always just go to your saves folder outside of the .exe and delete it manually, but I find this a lot easier and simpler. It is also better for new players.
3) Add an option to save it to your saves folder or just use it temporarily. Like, there could be a popup when downloading to ask "Would you like to save this to your save folders, or use it temporarily?" then there could be another option below it to choose your current selection every time or not, just so it doesn't annoy players whenever they just want to use the saves as temporary or permanently every time.
