Steam Cloud Save Management and Manual Back-Up Option
I'd like a Steam Overlay button as well as a Steam Overlay-responsive hotkey that can be manually changed by a user that, if used, it will take the game's save file (if possible) and back up it. Also having a button in the library screen to manage a game's steam cloud saves would be Very nice. Mainly just to toggle a save as not being used, to clear a single game's cloud save or to, even in there, manually replace the local save with that in the cloud or vice-versa.

I love Steam cloud but I want more manual control options that aren't hidden in the Properties menu, and I'd like to just have some games only have steam cloud back-ups happening when I click an overlay button or use a hotkey to trigger it.

After all, pressing F5 in the Steam Client when the inside isn't 'in focus' will restart Steam (because someone thought it was a bright idea to make it into a chromium web app) so why not just bring users more useful hotkeys that can function differently based on context? A Cloud Save Management window brought up via hotkey could be a really nice QoL feature especially if it was contextual so that if you're viewing a specific game in your library, it'll bring you into the cloud save management screen for that game, maybe holding F1 could display a list of the Steam Client's hotkeys for easy reference.

I like Steam Cloud, but I'd like its disabling to be either easier, or to allow saving to steam cloud to be manually-done.
