Hopes and dreams

1. legend2: customization
   1. (?) itemTpl support
      1. replace default item with tpl
      2. can I / should I sanitize it?
      3. support for $v, $d, $p
   2. (?) custom head
2. (?) validation of input
   1. check if required values are present
   2. message showing whole entry, when entry is invalid
   3. pre-sanitize values?
   4. sane info when JSON fails? Maybe dump JSON and show example with quotes-n-all...
3. (?) option to sort entries by value
