I have a campaign for an event, where I needed separate time blocks with a set number of tickets per time block. I created four separate campaigns to accomplish this, then a 'master' campaign with links to the other campaigns for purchasing tickets. Unfortunately there was no way to hide the 'master' campaign's Donate button. This creates a User Experience issue, being the first call to action on the page (when I want people to select a time slot and purchase event tickets). Disabling the button makes a user think that the event is over. It becomes even more of a UX issue when in a mobile context. For just this kind of scenario, it would be good to have a way to hide the Donate button.
