The instructions posted in FireFly's thread should work fine with Mist's version.

Anyway,
In showthread.php find:

$textareacols = gettextareawidth();

Below it add:

$clickysmilies = getclickysmilies();

Then in your showthread template find:

<! -- hackless quick reply -->

<br />

Below it add:

<script language="Javascript" src="vbcode.js"></script>
<script language="Javascript" src="vbcode_language.js"></script>

Still in the showthread template find:

<normalfont color="{pagetextcolor}"><b>Your Reply:</b></normalfont>
</td>

Replace it with:

<normalfont color="{pagetextcolor}"><b>Your Reply:</b></normalfont><br>
$clickysmilies
</td>

Find:

<input type="hidden" name="email" value="">

..and delete it.

Find:

	<input type="reset" class="bginput" name="reset" value="Reset Form" accesskey="r" tabindex="3">

Below it add:

<input type="checkbox" name="email" value="yes"><smallfont>Email Notification</smallfont>
