Please add option to disable/enable the the computer switch(flow feature) option by clicking some keyboard button combination.. for example CTRL+F
so the user can lock the mouse and the keyboard to specific computer and when user has some activity that requires him to move the mouse near the edge its not switching to other computer by accident.. so after that activity he enable the computer switch option back and switches between the computer without holding CTRL or something..
Basically the CTRL holding option, user locked to 1 computer until he hold the CTRL than the switching is enabled...
as for me I find it annoing to hold the CTRL button all the time that i switches between computers..
some times i have activity that involves intense switching so its annoying to hold the CTRL button for this..
