For players such as myself that have such a long list of neighbors, a simple "Select All" feature would be a wonderful addition. It should also be noted that sometimes when selecting neighbors, the checkmark disappears. When you put the checkmark back in place, check all of your other neighbors (those of which the checkmark will stay in place), then click send, you get an alert that says something along the lines of "Your request has been sent, but (insert number of checkmark-glitched-neighbors here) neighbors have not recieved the request as you have already sent them one today."
