Many hours have been invested in improving the overall performance and preparing the map for the hundrets of systems thare are going to be soon added. You will need to activate and deactivate the following functions, 'scroll', 'zoom', 'select' and 'adv.' (advanced). Don't forget to check out the 'adv.' (advanced) menu.
Give it a spin and please leave a comment here so I can further improve this project for you. Thank you.
