Out of the box, Miranda is a pretty plain instant messaging client. It doesn't have to be like that if you don't like it though. There are hundreds of plugins available, and hundreds more backgrounds, icons and sounds to add to Miranda. All are available for download from the File Listing.
The most commonly installed useful plugins are listed here.
- Popup Plugin/Popup Plus Plugin
Enables plugins to popup messages in little boxes when they want to tell you something. This is a service plugin, and on its own does nothing.
- New Event Notify Plugin
Will notify you of events (like incoming messages) in a popup. Requires a popup Plugin.
- New Status Notify Plugin/Contacts Status Notification Plugin
Notify you (using popups) when a contact changes their status and provide sounds for individual contacts.
- tabSRMM Plugin
Allows conversations to be in one window, using tabs, as opposed to one window per contact.
- History Plus Plus Plugin
History++ allows for easier navigation of the logged history of your contacts. It includes search, password protection, and saving as a text, xml, or HTML file.
- Auto Database Backup Plugin
Does exactly what it says, recommended for anyone who has important history/contacts in their database.
- Last Seen Plugin
A thoroughly recommended plugin that keeps logs of your contacts' statuses. It can also pop up a dialog box to alert you when a specific user changes status.
- Weather Plugin
Its usefulness is arguable, but it is popular. This plugin can retrieve the weather for a given location, and show it in your contact list, system tray, or as a popup.
