BoYagoob,
In the mean time, here are the changes you need to make to add a "Use Signature" tickbox:
Edit the
quickclip_replybox template (in the "QuickClip Templates" group) and find:
Code:
$quickclip_dropdown
Directly after that, add:
Code:
<label for="cb_signature"><input type="checkbox" name="signature" value="1" id="cb_signature" tabindex="5" checked="checked" />$vbphrase[show_your_signature]</label>
