Hi all,
I just want to suggest you some small visual improvements :

[1] Change default font to Lucida Grande. Now it's Verdana and maybe you can say that it's matter of taste but Lucida Grande is way more smooth, takes a bit less space horizontaly and has a bit bigger line height. All those things makes, for example comments listing way more readable.

[2] Add 10px padding to td.bugnote-public and td.bugnote-note-public
Those comments contents are choking there! And when you need to read hundreds of them, your eyes can feel bit tired, believe me :)

** Code ***

[1] :
td {
font-family:Verdana,Arial,Helvetica,sans-serif;
font-size:10pt;
padding:4px;
text-align:left;
}

change to

td {
font-family:"Lucida Grande", Verdana,Arial,Helvetica,sans-serif;
font-size:10pt;
padding:4px;
text-align:left;
}

[2] :

default.css line 86
td.bugnote-public {
background-color:#C8C8E8;
color:#000000;
font-weight:bold;
line-height:1.4;
vertical-align:top;
width:25%;
}

change to

td.bugnote-public {
background-color:#C8C8E8;
color:#000000;
font-weight:bold;
line-height:1.4;
vertical-align:top;
width:25%;
padding: 10px;
}

&&&&&&&

default.css line 88 :

td.bugnote-note-public {
background-color:#E8E8E8;
color:#000000;
vertical-align:top;
width:75%;
}

change to
td.bugnote-note-public {
background-color:#E8E8E8;
color:#000000;
vertical-align:top;
width:75%;
padding: 10px;
}

i'm attaching example how comments list looks with those improvements

regards,
Mike
