I think it would be great if i could have a checkbox in command wait until variable exists that if checked would basically send an alert that in x button x variable name with x timeout run out fully. Why? i have a lot of buttons that communicate with each other, one of them is not receiveing data before timeout runs out but there is no obvious fail in my system so it's quite time consuming to pinpoint exactly where and what is set incorrectly and i think something like this would speed up debugging.
