v1.5.0

Added

• Scrollbars on the tree and content panes — a vertical bar when there's more than fits, a
  horizontal bar when a row or unwrapped line runs wider than the pane. They show only where
  there's something to scroll, sit just inside the pane, and are draggable with the mouse
  (drag ↕/↔, or click the track to jump). Dragging the tree's vertical bar scrubs the selection.
• Horizontal tree scrolling so a long or deeply-nested file name can be read in full — via the
  horizontal wheel or by dragging the tree's horizontal scrollbar.
• Hide hidden files (.) — a toggle that drops dot-prefixed files/folders from the tree (handy
  in a $HOME full of them). Independent of the gitignore toggle (i), off by default. (#46)

Fixed

• The tree now scrolls to follow the selection — on a long list it used to stay pinned to the
  top, so moving the cursor past the last visible row selected files you couldn't see. (#45)

Thanks to @julianduque for reporting #45 and #46.
