Your comment really made my day, thanks for taking the time to leave us some feedback!
All of your ideas are awesome and pretty much all of them happen to be things we have planned to do already so that's super cool! In the next update which will be up either Wednesday or Thursday we will have a shop where you can upgrade your airplane (and other things too!) so you can fly further to new dig sites.
Being able to move all the tables is a great suggestion and something which we've added to our list of to-do's
So stoked that you like the concept of the game so much!! I hope you enjoy all the future updates coming your way :D
