Those familiar with clients, or users of MUSHclient might like to use 4D's own plugin. With this plugin you'll get a better view of the surroundings as you'll see the graphical map of the surrounding rooms at the right part of the client. 

At the bottom you'll find different bars that represent your remaining hp, mana-points and movepoints.

And of course there are some extra's like the avatars, the buttons that show you have a spell casted upon you, etc.

Special thanks goes to KaVir from God Wars II who made this specific plugin for 4D.

To those who already downloaded the plugin at previous times, it might be wise to download the seperate image-file and install it in the MUSHclient directory as it may hold other images than the original file.
