Messenger Plus! Live is the one essential add-on for Windows Live Messenger, period. After 150 million installations since 2001, when it started as a simple add-on for MSN Messenger 3, Messenger Plus! is guaranteed to improve your Messenger experience by leaps and bounds. You won't just get a couple of new options, what you'll get is a whole new dimension for the Windows Live Messenger software.
Thought out end-to-end to improve and enhance your instant messaging without getting in your way, Plus! adds lots of capabilities to Windows Live Messenger. It lets you use them at your will from the simple Plus! menu that gets added to every Messenger window and a couple of new buttons you'll find within the Messenger interface:
Custom Sounds
The Custom Emotion Sound feature brings sound integration in Messenger to the next level by allowing users to send their own sounds during a conversation. Sounds are played instantly on both ends and are transferred automatically and transparently when needed.
New emotion sounds can be easily created from existing sound files (such as MP3s) or can be recorded live from a Microphone or other audio source but, if sound authoring isn't your thing, thousands of sounds can be found in the public database or imported from sound packs
Colors, formatting and commands
Messenger Plus! gives you the possibility to choose any color you want for front and background, and add formatting, such as bold, italic, underlined and stoke-out. It also lets you control almost every Aspect of Messenger via text shortcuts called commands, much like the ones in traditional IRC chat rooms.
Tabbed Chats
Use a tabbed web browser? Even if you don't, you might find tabbed conversations useful for organizing your chats by converting a MYRIAD of windows into a simple single one. Vertical tabs on the left, normal tabs on the top. You name it.
