We have a very long development to-do list of all the features we would like to add when we have the resources to do so. In the meantime, use Bookmarks to tag recipes. You can set up category tags such as dinner party desserts, vegetarian dinners, Thanksgiving sides, etc then whenever you see a recipe you want to save for the future you add that Bookmark. Then when you are for example planning a dinner party, you can filter out all the recipes you saved.
You can also set up Bookmarks as menus then add that tag to all the recipes for the event. In order to find them easily, start with the same name then add either the date or the occasion e.g. Menu - brunch spring or Menu - dinner 4/11/16. Then add the recipes to that menu and you can recall it in the future. Add Notes to the recipes (you can make them private if they just relate to you) and you have a record of the event.
