 ### Basic Flags
-`-s` should only be used for supported terminals and if the user wants to start a tmux or tmuxinator session. `-a` should be used to set up WM specific rules (which are required for the --width, --height, --xoff, and --yoff flags to work properly; see below for supported WMs). Long options require using `--opt=<arg>` as opposed to leaving a space. Refer to `tdrop --help` and the manpage for more complete instructions.

 \fB\-m\fR, \fB \-\-monitor-aware\fR
 This option only applies for dropdowns (not auto-hiding and auto-showing). Specify that width and height percentages should be relative to the current monitor. If the monitor changes, this option will cause a dropdown to be resized to fit the given percentages. A negative argument is also allowed for '-w' and '-y' with this option (e.g. '-m -w -4') in which case the determined value will be that many pixels less than 100% of the screen size. This fixes the problem where 100% width may actually go over the screen due to window borders/decoration. Note that this option assumes xrandr is being used and requires xrandr to work. (default: false)
