Replying to Stuff to try at open gym?

I go to an open gym gymnastics thing every sunday and I want to make a list of stuff to learn. I can already backflip and wall flip and today I started learning j step gainers. The gym is kinda limited but it has a mini tramp, spring boards, spring floor, lots of mats, beams, and those multi level bars that I don't know the name of and other stuff.
Anyone else go to open gym?
