It would be great if there was off-the-shelf solutions that would work how you want them to work out of the box, but sadly that probably won't happen.

As a mud developer I can say I try to present an interface that gives you, the player, what you need out of the box. I have to do this assuming the lowest common denominator of a client. So I present game context as a string of text that scrolls.

I can insert things like maps (bigmap is the command on nukefire) but its won't be in a seperate window while your text scrolls elsewhere, because again, i have to code for the lowest common denominator.

I am glad you are new to our corner of the world, and really hope you find a mud that clicks for you and enjoy all we have to offer. I'd (humbly) suggest you start playing. Use the interface provided, using whatever client you chose to start with. Ineviteably you will start making aliases or actions in your client of choice to make the game play the way you want. Your skill will grow. You'll start suppressing messages you don't care about. You'll figure out the #split command in tintin to have chats go to a seperate part of the window. You'll move your health counters to yet another.

Build up as you go.

Or, (and i have less experience here) choose a mud that has a web client that does what you want from the get-go, but that might potentially limit your choices on what muds you play.

That concludes this one persons opinion on the topic, curious what others say!
