That works, but unfortunately it also hides the unavailable actions of active projects. If you want to separately hide future or on-hold projects, but still see all the remaining actions of the active projects, there's no way to do that in Project view currently. Hopefully that will change in future versions. Use Contact Omni in the gear menu to submit your request if you'd like that functionality.
