edit the template search_resultlist to add the text to the top (thread, replies, etc).
To narrow the replies/views column, here is the current css to change:
HTML Code:
.threadbit .threadstats { padding-top: 8.74px; width: 15%; word-wrap: break-word;}
If you reduce that, you can increase this by the same amount:
HTML Code:
.threadbit .threadlastpost, .threadbit .threaddeleted { font-size: 12px; padding-left: 0; width: 20%;}
