Which of these should we build first?

[MTSistemi]

Four things are planned and none is started. They are roughly the same amount of work, so
the order is genuinely open — and we would rather it were decided by the people who use the
board than by whichever one we feel like on a given evening.

Pick with a reaction:

	Option	What it means
👍	Installation guide with screenshots, in four languages	A step-by-step guide with real installer screenshots, reshot for each language. The single most requested thing so far.
❤️	Snapshot management in a window	Btrfs Assistant is already in the system: put it in the menu, theme it, translate it. Listing, creating and restoring a snapshot without the terminal.
🚀	Games on an external drive	A selector to install games on a USB SSD instead of the system disk — including the Flatpak permission for Steam, which is the part that catches everyone out.
🎉	Configurable HUD and fan curve editor	The on-screen panel builds itself from the sensors actually present, and the fan curve becomes editable instead of "manual percentage or automatic".

If none of these is what you actually want, say so in a comment — that is also an answer.
