Hi all! I just released my lightweight GUI for TradeDangerous that I've been working on. It's not a full GUI, it just shows the TradeDangerous output in a scrollable window, but it's easier to use than the command line (at least for me ). It also has full auto-completion when typing system/station names and commodity items, and it can keep a log of your system jumps to a logfile (if enabled in the Settings tab). More information is in the readme.txt in the zip.
It's written in C#, so it's Windows-only and requires Microsoft .NET Framework 4.5.1. You just drop it into your TradeDangerous folder and go. Screenshot is below:
There are a few other things I want to add to the next version, including a tab to enter or update station data. You can download TDGUI from my site's download page here.
