Issue

All subtasks show up on main page.

Server Setup Information:

• Wekan version: 1.69 (snap install)

Problem description:
It would be great to have the option to collapse subtask boards. I am member of a board I was invited to, and the user made heavy use of subtasks to the point where it takes up a considerable portion of the main page. It would be great to have a way to either collapse or hide these.
