• allow a case-insensitive tag search when searching for links.
  • sort tags in a case-insensitive fashion in the tag view.
  • add a feature to normalize tags. For example, I have 5 occurrences of "Alternative", 2 of "alternative" (lower-case) and 1 of "Alternatives". Right now, I have to edit the erroneous links to add the correct tag and delete the old ones.
