So I have a semi-auto coco bean farm, and what really bugs me about it, is sometimes the server clears all of the items that drop, as soon as I click the button to clear the beans. I don't know if it clearing is scheduled or mods do it, but I think an easy fix to this is to have a warning one minute before the clear. I know a lot of servers have the clear lag feature, but also have the warning to avoid this frustration. Even if every hour you clear, just have there be a warning a minute before, half-minute before, 10 sec before, 9 sec before,8,7,etc. It would maybe crowd chat a bit, but I think it would be a really helpful addition.
+1 this would be very, very helpful. Maybe even a command like /lag messages, which would toggle the lag clear messages if you find them bothersome.
