I just thought of an idea to help make editing a system easier to test and to decrease errors in development. How about making a "System Locator" (or whatever other name you would call it).
Basically, at the top of the star map system editor, there would be a drop-down box. The first option would be 'normal' (which is where the drop box starts at when you enter the editor), where the system editor behaves normally as always. The rest of the options in the drop box would allow you to identify which systems contain certain information. For example: if you selected 'commodities' from the list, all the system graphics would turn into blue circles except those containing planets with any type of commodity being sold, they would turn green (in simpler words, if a system sells no commodities then it remains blue, if else turn green). Then another drop box would appear next to it where you could (if you wanted to sharpen your search) specify the certain commodity you wanted to locate. Once you select the commodity your looking for, then every system containing a planet that is selling that certain commodity turns green, while those that don't turn blue. Then if your looking for commodities at certain prices (High, Med, or Low), another drop box could appear for that. This would be helpful for setting up trade routes and to test to be sure all your systems have the correct commodities, instead of having to play the game and go to each and every system.
There are plenty of other things you could locate, pretty much any information you could get from a s˙st or spöb could be located. The most useful things to locate would be governments, commodities, tech levels, and many others.
I know little on the type of programming your using, but I'd imagine it would be very hard, if not impossible to check information from every single planet and system, then display it efficiently without a lot of thinking time. But, that's why its an idea, and it would be on the bottom of the to-do list anyways. Though it would be another really cool and useful feature MC would have over other editors. Tell me you guys like the idea! (THEN tell me the technical difficulties :rolleyes: )
