So, Trillian is currently my IM app of choice on any and all platforms. I find the UI is really nice and not as unintuitive as some people claim (its a subjective thing at best anyway). I find the app is responsive and reliable, and I havent had any of e problems with lag or crashing that I saw some other people mentioning. I have some constructive criticisms though, and Ill spell them out here. 1. Lack of a Return key. In the mobile Trillian app, both on iPhone, and while running on iPad, there is no method to insert a new line into a message. Instead of a Return key, we have a Send key. Im not necessarily saying this is bad. But it would be great if the send key could be relocated, and a Return key left in its place, OR, perhaps an even better solution would be to allow some kind of "shift + enter" functionality for entering new lines like on the desktop version and in many other desktop IM applications. If youre sending a lot of thoughts to a friend, its nice to have a method of breaking them up. The ability to start a new paragraph without sending the previous one is kind of important. 2. Determining exactly when a message was sent. The Apple-esque relative time stamps that find their way into the conversation log are great. I really do love them. But there needs to be a way to determine exactly when a message was sent, to the second. This is also a functionality that I cant seem to fond on the desktop app either. Being able to mouse over and get a popup would be great. Im not sure how to translate that to mobile though. Perhaps some kind of floating label that pops up when you press and hold on a message, above or beneath the black context menu. I do still give this app 5 stars. It does deserve them. But there are improvements to be made, and if Cerulean wants to keep that rating, I hope it will strive to keep improving the app.
