'Taglist: Exuberant ctags (http://ctags.sf.net) not found in PATH. Plugin is not loaded.' error in MacVim (Janus)

After launching MacVim you may get this annoying error message:
'Taglist: Exuberant ctags (http://ctags.sf.net) not found in PATH. Plugin is not loaded.'

To remove this you have to install ctags which you can download from http://ctags.sf.net.
After you unziped it, you have to set the Tlist_Ctags_Cmd variable in the .vimrc file to point to the ctags folder.

let Tlist_Ctags_Cmd = '/usr/local/bin/ctags'

After that you have to restart vim and the message should not pop up again.

Tapping on <label> in Mobile Safari

Tapping on <label> does not auto-focus linked in Mobile Safari but If we add an empty function as clickhandler it works fine.

<input type="checkbox" id="test" name="test">
<label for="test" id="test_label">This is the label</label>
<script>
  document.getElementById("test_label").onclick = function () {};
</script>

Checkbox/Radio button size on Android Safari

You cannot change checkbox/radio button width/height on Android in Safari because it is tied to the OS.

But since the default ones are so tiny that you may need bigger buttons.
Here is a simple trick:

input[type=checkbox] {
  -webkit-transform: scale(2,2);
}

Please note that if you set up values bigger than ~2 then the yellow outline will look weird.
