No Market Notification
by Nick Rogers

Overview
========
This OXP aims to make it clearer to players who are docked at a station that has no market available. Instead of showing a list of commodities with zero values, a simple message is displayed, informing the player there is no market available, and then sending the player to the F5F5 Manifest screen, where details of the contents of the player's hold can be viewed.
