gemini: Keep the views' presets constantly in sync

This ensures that the most recently used preset is actually saved
properly across sessions. Timing issues can be fun at times (because
of how the widgets are parented, the not-current view gets deleted
last, and thus that is the one who's preset gets stored... so, keep
them up to date, magically stuff works)
