Allow personal lists
The new lists app is great but i'd like to be able to have personal lists as well, perhaps as an item on the left hand side alongside calendar etc.
I'd like to be able to use the lists feature to maintain my own todo lists that are separate from a channels or teams lists
As an extension of this, the personal lists view could also provide easy access to lists in channels that you are a member of?

Personal Lists are a thing already in the lists app. When you create a new list in the lists app, you can save it to My Lists.

Sounds like you are looking for the new Tasks app (currently called Planner) which is the Planner app and the To Do app combined in Teams now (or via web at tasks.office.com).
It will show you all Planner tasks assigned to you across all Team, gives you access to all Planner tasks in all Teams you are a member of and, allows you to maintain personal To Do lists to track your personal tasks.
