I've discovered a bug with sortable columns and toolbar search.
When you have toolbar search enabled and a mix of selects and textboxes you can see that the toolbar search options do not properly follow the column header after reordering.

The bug only affects webkit-based browsers (i.e. chrome / safari) as far as I can tell (Opera and FF are working fine).
Reproducible in jqGrid 3.7.2 and 3.8.2.

Here is the code to reproduce:

$('#mylist').jqGrid({
