This will move the red "Pin" back to the left, where it used to be:

But first, you have to change the existing code as such...

Change:

/* Makes all grey buttons look shaded */
.v-Button {
box-shadow:5px 5px 5px rgba(0,0,0,.25), 0 0 20px transparent inset, 0 0 1px rgba(255,255,255,0.5) inset;
}

To...

/* Makes All Grey Buttons Look Shaded */
.v-Button--hasIcon,.v-MenuButton,.v-ResourceItem-badge,.v-ResourceItem-rightCol > button {
box-shadow:5px 5px 5px rgba(0,0,0,.25), 0 0 20px transparent inset, 0 0 1px rgba(255,255,255,0.5) inset;
}

and then underneath that add:

/* Puts The Pin On The Left */
.v-Thread .is-pinned {
position:fixed;
top:-8px;
left:-27px;
background-color:transparent;
}

/* Puts The Pin On The Left */
.v-Thread .is-unpinned {
position:fixed;
top:-8px;
left:-27px;
}
