  ## User Interface

  ### Fixed up the tabs on pages

  The code that draws the tabs on the VPE canvas now produces rounded tabs even on Windows running the Exceed X server.

  ### Tool selector is now a tree view

  The tool selector and categories have now been combined into a standard tree view. Click on the (+) next to each category to expand the list. Click on the (-) next to an expanded category to collapse the category.

  ### Preferences file for saving state

  Now at the end of each execution, OpenDX will add the network to a list of previously opened networks for the new "Open Recent" menu option under file. The preferences all save the state of the tool selector so that it is the same when restarting dx.

  ### Automatic graph layout of modules

  New mode under the Edit menu to automatically layout a network page.

  ### Undo now available in VPE

  An undo option for the VPE is now available. Every node or annotation move is recorded and can be undone from the Edit menu or via the shortcut (Ctrl-U) or (Ctrl-Z) depending on your keyboard layout.

  ### Cursor keys now move modules on canvas

  The cursor keys now can move the modules on the VPE canvas. Select a node(s) or annotation, then use the up, down, left, or right arrows to move the selected objects 1 pixel at a time.
