Sill 0.4.4

• Themes: Each card in the Appearance theme picker previews its own
  theme. The selected row, the text colour and the colour wash on every card
  used to follow whichever theme was applied, so with Oilslick on, all seven
  cards showed Oilslick's wash, and Frost Light's pale card had white text.
  The glass and chroma sliders and the chosen font still carry into the
  previews.
• Launcher: The Sill menu button in the bottom left sits flat on the
  footer, like the Open and Actions keys beside it, and lights only on hover
  or while its menu is open.
