0.5

_Version 0.5:_ Sept 29, 2013

• Undo/redo support!
• Switched to URLON-encoding for the permalinks... since it mostly uses
  URL-safe characters, it results in significantly shorter URLs.
  • I'm not 100% sold on this... it still results in pretty ugly links. But at
    least they're shorter.
  • Note that the old permalinks should still work (since the data format
    didn't change... just the encoding).
• Alt+click is now allowed wherever Ctrl+Click was previously allowed (helpful
  for Mac users who can't Ctrl+Click).
• Shift+click will now "extend" the selection (linearly, in left-to-right
  fashion).
• Similarly, Shift+J/K will extend the selection.
• Ctrl+A will select all keys; ESC will de-select all.
• A couple of small bugfixes.

0.4

_Version 0.4:_ Sept 28, 2013

• Miscellaneous bug fixes and UI tweaks.
• Marquee select a bit easier to use, since it continues to track the mouse
  anywhere over the browser window.
• I've added pre-baked "ISO Enter" and "J-Shaped Enter" keys to the "Add Keys"
  dropdown.
• "Help" dialog to show available keyboard shortcuts.
• Code now on GitHub for proper versioning and stuff.
