I would like to be able to insert pre-set or new html snippets.

e.g. If I want a table then I want to click on the plugins menu and then insert table then it would input something like this:

 <table style="width:100%">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td>
    <td>50</td>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td>
    <td>94</td>
  </tr>
</table> 


I would like defaults along with the option to insert and change my own snippets.

There are several plugins for Notepad++ that provide this functionality. I therefore won't be adding it to the HTMLTag plugin.

Here are the ones I've got installed:

  *  Snippets ([https://www.fesevur.com/nppsnippets/])
  *  NppPlates ([http://sourceforge.net/projects/notepad-plus/forums/forum/482781/topic/5333716])
  *  QuickText ([http://sourceforge.net/tracker/?func=detail&aid=3009773&group_id=183263&atid=904542])

More are available via the Plugin Manager.
