v10.3.0

• Remote Play's Settings open over the stream. Every Settings button (on the picture's bar,
  beside Start, in the menu) opens the same panel: at the right edge on a computer or tablet, a
  sheet from the bottom on a phone. In full screen it opens inside full screen, so the game keeps
  showing and playing next to it, and nothing leaves full screen any more.
• Easy to close: ✕, Esc, a click or tap beside it, the Settings button again, or a swipe
  down on a phone. Esc closes Settings instead of pressing ○, and never leaves full screen.
• Settings in four tabs: Picture, Sound, Controls (with controllers, controller buttons and
  keyboard keys) and Session. It opens on the last tab you used, and the arrow keys move between
  tabs.
• While Settings is open, the game gets no keys or controller presses, so arrows and typing
  work in the settings; play goes on as you close it.
• Picture, frame rate, video decoding, video format and Keep playing can be changed during a
  stream. They say "Applies when you start again"; everything else applies at once.
• Switch saves are backed up. The saves of ProsperoEden, the Switch emulator (PPSA99008), are
  backed up with the PS5 saves, locally and to a server; "after a game closes" means after
  ProsperoEden closes. Thanks to EnriqueWood (#600).
• Switch saves in Saves. "Switch games (ProsperoEden)" lists each game's save per profile,
  with Back up now and its local and server backups, so you can restore one in the app. Close
  ProsperoEden first: a restore is refused while it runs.
• A refused restore says why under the game's backups, not only in Notifications.
• Fixed: a restore could leave old files in a big save. A save folder with more than 256 files
  was emptied only in part before the backup went in, so stale files stayed mixed with the
  restored ones. The whole folder is emptied now.
