Simcoin Chrome extension that monitors both simxchg and simtalk and displays orders and new posts.
This extension periodically fetches simxchg orders and displays the price either in satoshis or in USD per 1 million SIM.
In case of satoshis it displays top sell and buy orders.
In case of USD it displays the average price = (sell + buy) / 2.
It also fetches the latest posts from simtalk and displays red notification mark if there are new posts since you last clicked 'Visit forum'.
