I 5box shamans. My monitor setup is the main on 1 and the 4 others split into 25% quadrants on 2nd monitor.

My main is a skinner/herbalist. My 2nd char (upper left quad) is my miner/tailor. I had a lot of problems missing mining nodes because the little gold dot was so small that I would miss them.

I found an addon today called BigMiniMap; http://www.wowinterface.com/download...p?id=4095#info

I found that I could blow the minimap map up by close to 3x on the secondary window and easily see when I got near a mining node while keeping the main window focused on herbing nodes.

I hope this helps someone else who may have been looking for something like this and if it's been posted before, my apologies.
