Description

Currently xfce-settings hardcodes touchpad multi-tap gesture buttons, and provides no way to disable that behavior.

I usually use two-finger middle click and three-finger right-click, but xfce4 overrides my settings on Xorg.conf synaptics settings and hardcodes them for three-finger middle click and two-finger right click.

From http://git.xfce.org/xfce/xfce4-settings/tree/dialogs/mouse-settings/main.c: tap_to_click = gtk_toggle_button_get_active (GTK_TOGGLE_BUTTON (object));

/* format: RT, RB, LT, LB, F1, F2, F3 */
data[4] = tap_to_click ? 1 : 0;
data[5] = tap_to_click ? 3 : 0;
data[6] = tap_to_click ? 2 : 0;

Xfce should, whether provide a way for selecting data[5] = 2 and data[6] = 3, or disable that setting completely and let xorg/synaptics do the job.
