Possible improvements people could work on:

- [FEATURE] have an option (e.g. --no-proxy),
  that lets linkchecker ignore all proxy settings in the
  environment. And it would be nice when there where an
  environment variable (e.g. $NO_PROXY) that holds a
  comma-separated list of hosts, that should be contacted
  directly and not over a proxy.

- [FEATURE] Prevent LinkChecker from taking too much CPU resources.
  Windows:
  http://msdn.microsoft.com/library/en-us/dllproc/base/scheduling_priorities.asp
  win32process.SetPriorityClass(
                              win32process.GetCurrentProcess(),
                              win32process.BELOW_NORMAL_PRIORITY_CLASS)
  Linux:
  os.nice(+5)

- [INSTALL] build .mo file with improved msgfmt.py from roundup

- [USAGE] rethink intern/extern stuff

- [BUGFIX] when an URL is found in the cache and it has a broken anchor,
  the broken anchor name is not displayed as a warning

- [USAGE] make a nice GUI for linkchecker

- [FEATURE] warn if overall size of page (including images/flash/etc.) is
  too big. Right now, the page size is only html content.

- [FEATURE] Option to save downloaded pages. This could also be used to
  build an internal cache, however there are already a plethora of
  caching proxies we could use for that.
