FLCompanion is the most important tool for me during playing and you make it even more amazing. Thank you!

I've got some suggestion for you to improve it even better:
- Currently "Total" line in Trade Route List works only if station on the beginning and on the end is the same. I think it should appear for every route that is composed.
- Saving of trade routes would be very helpful.
- I sometimes miss an option to look for all available routes from selected system.
- Another thing is some problem with <Mining Operation> that can be set. After setting more than one program starts calculate routes with each mineable good choosen from selected system. You can see here what I mean: https://imgur.com/a/SWX6MtJ
It shows routes with Xeno Relicts and Niobium Ore from Mining Operation that I set in Omega-3. I think it can be solved by adding an option to delete previous Mining Operations.
