Customization not extensive enough

Customization of My Work not great - Workaround is to create own dashboard but MyWork should be able to effectively be the same thing.

I would like to have the ability to add / remove columns in My Work when customizing it. We currently use (2) different people columns and designate the columns as

Column 1: Responsible
Column 2: Assist

I agree and I would personally like the ability to filter by status.
We have statuses like ‘With Client’ and ‘Waiting on feedback’ which would be useful to remove from view so I only see the work I still have to do, rather than a long list of ‘Overdue’ items which have been completed from my side.
