I would like to suggest a 'select all' button at the top/bottom of the trade routes list so you can quickly switch all trade routes off/on without having to laboriously go through them one by one.
OMG I was literally complaining about trade routes today.
I would like an option to create all trade routes (1 trade route per hour * 24 hours every day) to save time. as it is just time consuming and stupid to set 24 trade routes per villa...
Thanks for your suggestion, I have added your wish to the weekly feedback.
