For individual actions I want to hide, I give it a start date in the future.
As long as you are looking at available actions and not remaining, the actions will be hidden.

For projects that I am not working on, I place the project on hold. As long as you are filtering by Active projects, you will not see the on hold projects.

The stalled projects filter deems that any project that has actions, but the actions have a start date in the future, then it is stalled. To me this is not correct. If I have actions in the future, my project is not stalled. A stalled project to me is a project or sub-projects that have no children actions to move it forward. I do not currently use the stalled projects filter.
