-> When Finder changes labels, our icons don't reflect that. Why?
-> Need to follow symlinks when getting icons and doing folder-detection.
-> Use the access() Unix function to determine whether a file can be read
    from/written to etc. Or isFileWritableAtPath/isFileDeletableAtPath etc. and
    pick the proper icon based on that.
-> UKDV focus rect leaves artifacts when auto-scrolling.
-> Tyler wants a drop shadow on preview icons
-> UKSidebarController: Sidebar can contain several items with same name, which
    aren't distinguished properly right now
-> Why do icons have jaggies again?
-> Turn sidebar mountain view image into some sort of DnD "shelf".
-> Can we move tool tips onto the names, like in Finder?
-> How do we detect/eject removable media?
-> Allow toggling "show invisibles" option, allow editing "visible" flag.
-> Move controllers, info windows etc. that use paths to use URLs, so they'll later
    be able towork with FTP file system data sources or whatever, too.
-> Create an inspector based on the info panel and its protocol.
-> Should we have a "Merge Folders" menu item?
-> When the icon sizes change, either also scale the UKDistView's margin size,
    or alternately, subtract it, scale, and re-add it, so it's ignored. Otherwise
    the first zoom after an icon resize causes the icons to jump.
-> Change IconKit's alloc to return a singleton, and only really alloc a new
    object *after* we've made sure an object for that particular IconRef isn't
    in the cache already.
-> Find out why UKFNSubscribeFileWatcher doesn't notice when Finder changes
    stuff. (USE_KQUEUE=0)
-> Uncouple the position stuff form UKFSItem and instead use some sort of
    dictionary, so each view can store its own position for an item. Move the
    controller stuff that is related to display only into a new UKViewer class,
    so we can really swap views in and out.
-> Find out why sidebar doesn't correctly update when disks are inserted. Looks
    like it updates too early?
-> Make sure failed deletes give an error.
-> Give warning instead of empty windows when user doesn't have permission to view a folder.
-> Redo menus. Sidebar and "Go to"
  UKFolderController: Settings changes and window moves need to change
    lastChanged so they get saved.
  Fix the make_svn_version_header.sh shell script. It can't cope with several
    revision numbers being in the entries file, and I couldn't get tail to
    extract a line to at least partially fix it.
  Either fix naming of UKMainThreadActionQueue, or find out why the heck I
    thought it was a good idea to queue icon loading on the main thread... ?!
    We don't need a main thread queue anyway, because we have
    performSelectorOnMainThread: in NSThread ?!!!
  When a directory changes, update the existing UKFSItems instead of completely
    rebuilding the items.
  Find out why we get a new controller each time we choose a "Go to..." menu
    item.
