First leaf with inner fenestrations. Also a 1.5 year progress update on my first monstera

My first monstera is really getting big after only a year and a half. I’m no monstera expert but it seems to be growing well. I never setup and supports so it’s growing sort of “bushy”. I believe it is actually 3 plants in one pot. I don’t really have the time or space to untangle them but am considering just letting it ride and just chopping and propping some large pretty leaves to try to create a plant that grows more cleanly and vertically. Let me know what you guys think! I don’t do too much special to it but water every two weeks or so in the summer and then dial back to every three weeks in the winter.
