I would like the ability to create a view that is FILTERED based on the value of a custom field

When I create a view of a task list that is sorted on a custom field, I would like the ability to filter the view so that all tasks are not present in the view.

In this way, I would be able to have a view that includes tasks related to a certain topic (designated by a custom field) in one view, while another view could include items labeled differently.

This feature would co-exist with the ability to name and save views of lists and make them selectable from the same dropdown used to select the sort today.

<I understand I can filter with an advanced search, but this is entirely different than having a view available that is pre-configured to be sorted and filtered in a particular way>

What you are describing looks a lot like tags and views you see when you click on a tag isn’t it?
