Trellis Ideas

Could you make site sections “hideable”? We often need to build and prepare content in advance for different parts of an event we plan to feature on the homepage. However, we can’t do that right now because publishing is required for other changes (like adding ticket types or items for sale). As a result, we have to either delete our work or save everything until the last minute to prevent it from being visible to site visitors. *As a bonus, if they could be "timed" so we can set it and forget it knowing the site will make that section visible the moment we planned and a person is not micromanaging it.
