Hi @CThomas,
Currently we are working on the next version of 1View which will have the support for sub-items. It will be mostly released within a month if everything goes according to the plan. It is packed with more advanced features and it will resolve most of the current issues.
Until then you can checkout our new app “Team View” which already has the sub-items support and it can be used to visualize tasks among different team members with a set of filters across multiple boards.
