This app is so behind!!

As a new YT creator for my new business start-up this app is a total mess am not an app I want on my phone, but I need it. Here are a few suggestions for you:
1) Add 3D Touch quick actions, your own YT app has it, so why not the Studio app?
2) Comments are a MESS fix them
3) Bad user interface and bad design choices
4) Laggy, slow and not something of googles standards

Please use these suggestions as something to work toward!! Thanks ?
