Similar Programs have been done before, but none modify components and facilities at the same time...
There is Krsqk's editor, which is useful for creating a multiple component set (such as mega meson bLasters 1-5).
Krsqk's Editor
There is the editor that is on the SEIV Gold CD. that is useful only for creating new components from scratch it does not show u the entire tech tree though (neither does Krsqk)
Then Lastly there is my component editing program. It shows u the entire component tree, lets u view/edit components and has features similar to the ones u have nominated. It does not show the facilities tree, but does read in the abilities.txt and techareas.txt files for loading on drop lists when u are using the program.
My component editor
Take a look at the ones ive mentioned, and by all means create your own editor if you wish. You might think of a few ideas after looking at the other programs, and even if your program isnt commonly used u might have fun making it anyway...i personally found making my program was quite interesting and enjoyable
