--tab and --drop-down are a bit confusing in some cases
Running xfce4-terminal --tab --drop-down
when no xfce4-terminal instances are running opens a new dropdown with 2 tabs.
The same command produces only a single tab if there is an existing instance of xfce4-terminal
, but no drop-down.
This is caused by win_attr->reuse_last_window
. A rewrite of the options handling code is probably required to fix this properly.
