Glad you liked it! :-) The update will be released in the next 2-3 weeks, usually every 2 weeks I release an update, but sometimes it takes longer if there is more content, or it is more complex than usual.
Of course, you can make suggestions :-), but I want to note that there is a kind of "queue" of suggestions, if you want yours to get into the game, then it is better to subscribe (like a paid subscriber), otherwise everything can be delayed.
You can write them right here, I will answer you whether I can add it to the game or not :-)
