as I replied here:http://tmp.garyr.net/forum/viewtopic.php?p=39160#39160
"open new tabs next to current one" does not produce fx3.6 default behavior,
there are differences in sources from which tabs open relative. Please comment.
yes, there are differences
Can you allow the fx3.6 default behavior to be selected or configured?
Ideally TMP options would let you select the source of tabs that open relative, this way not only the fx default but current and any other behavior could be configured.
