Sorry for the delay in notification. I have uploaded the new version of your coach composition widget also renamed it as "Coach Composition and Sitting Arrangement Gadget" so that along with coach you can see the sitting arrangement of each coach. The new version with some modification such as for reverse composition you need not to click any button it will automatically print below. For adding reserved coach you have choice to add coach in ascending and descending order with a slider and if you want to remove coaches just set the slider to 0th position. Soon some more modification will be implemented I just want to introduce this on this dipawali but some how got delayed. I hope you will enjoy it and just let me know if any error/issue persists.
