Folders for tasks within a project

Hello, I have a project that has enough tasks I had to break it into 2 different projects to be able to use the UI properly. There are 29 tasks for the project and as soon as the list of tasks goes over 17 on my phone screen, the ui starts getting janky and it becomes difficult to move and rename any of the tasks in the project. This made me realize that having folders that behave like the collapsable If or For actions would alleviate my issue, while also making organization within a project better. Cheers.
