Focus button for each task list

The idea of this is when I go to a task list that has a lot of teams working on things, and even within my own team we have multiple tasks, it would be nice to be able to hit a button and just have the rest of the tasks disappear. I don’t want to re-filter, or re-sort, I want everything to stay as-is, but just remove from my view everything that isn’t assigned to me. It’s just a way to focus in on my work for that project, without having to mess with the filters/sort. As a matter-of-fact, I think it would be cool if it worked on every project I go into, in other words, when I turn it ON, it says on no matter the project I go into, and then I have to toggle it OFF to see the rest of the project.
