I am posting each of my suggestions separately. I realise that makes a large number of posts, but it ensures that no suggestion gets lost if there are a lot of comments.

Suggestion 12: For ‘captured’ heroes, it would be helpful to have a ‘lock’ button on them – I currently have a senior hero that I will be activating soon, but not until I get more of the uncommon or rare equipment for him. I am currently afraid that I will accidentally delete him.
