Currently TotalTerminal will drop down the visor/terminal from whichever monitor currently has focus. this is sufficient behavior, but because the secondary monitor size is substantially different than the primary monitor (typical for many laptop users), so the terminal size changes depending on which has focus, which is… kind of annoying. Please consider adding a preference option that allows me to explicitly specify a monitor that TotalTerminal should always use, regardless of focus.
In TotalTerminal preferences there is a combo-box “Screen”. I believe that is what you are looking for.
