I never asked for any new features, you left out where I said to simply have a place to type the name of the star under the template.
You "never asked for any new features," and your proof is that I left out where you asked for a new feature to be added to the editor. Yes, I find your argument that you're asking for a bugfix rather than a new feature quite convincing.
Does the editor name your home star correctly?
Answer: NO - It names the star exactly the same name as the homeworld. In my case, my star's name is Earth which, as last check, is not the name of our local star, therefore it is incorrect.
Conclusion: BUG
Is there an entry field for a star name? No.
Is there evidence that the editor was intended to allow the player to name the home star separately from the home world? No.
Was the ability to name the home system separately from the home world an advertised or documented feature of the editor? No.
To appearances, then, the editor is working as intended. Therefore, the inability to name the home star separately from the home world is not a bug; while it is a 'missing feature,' it is not a feature that the editor was supposed to include.
What you are claiming is more or less like claiming that it is a bug that NotePad doesn't support embedding images into a text file since there are times when I might want to include an image in a text file. It's certainly a feature that NotePad could have - after all, MS Word, which like NotePad is primarily a text editor, supports embedded images - but the lack of this feature is not a bug in the program, it is simply a product of a decision about the scope of the editor.
Also, by your argument, the inability to name the other planets of the home system or set how many of them there are during custom faction creation is also a 'bug,' since, after all, the planets of the Sol system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (and Pluto, if you come down on that side of that argument), not Sol I, Sol II, Sol III, Sol IV, Sol V, Sol VI, Sol VII, and Sol VIII (and Sol IX), and certainly not Sol I, Sol II, Sol, Sol III, Sol IV, Sol V, Sol VI, and Sol VII (and Sol VIII), or in your example a similar set of names but using Earth in place of Sol. Obviously if I want to create an alternative human faction based in the Sol system it must be a "bug" that prevents me from spawning up to eight (nine) planets in the Sol system and giving them the appropriate names, rather than having some random set of planets named as (home world name) (Roman numeral) orbiting a star named (home world name) and in the same system as a planet named (home world name), rather than this being a feature outside the scope of the editor.
