Every error in an Apple Application app or whatever has like an error code along with it so that they know on their end easier What's going on. Toast messages should be Closeable if the users impatient I can get impatient sometimes and they don't want this piece of UI sitting on top of your application. There needs to be a clear close x button or whatever or you can just click it and have it disappear right? Another thing is like timeouts and I think we can Group this with manual close versus auto close Yeah, because this is one thing that you should have both of in my mind in my mind Your toast message should becloseable but also setting a timeout  is interesting.
