I'm not sure that this is the right way. It is true that it's not so easy to find the really good crafts between all that starships and stuff like them. I think you can't Change the mind of the Community, so we need a different way. I think (and i've read this a couple of Times Here) we need much better search and Filter Options, and much more tags. Take a Look at simple-Planes and the number of Tags they have. And they only build Planes, boats and cars, so SR2 should have a lot more Tags than SP.
I think the search-system needs a complete makeover.
To Play the devil's advocate, i have one qustion:
For how many players, Spaceflight simulator was the first game in this Genre?
I guess that many players go the way over SFS to SR2. After playing awhile more and more player are bored and they look out for a new challenge, and here we are.
So don't be too hard with SFS, many players wouldn't be here without him.
I thought there's one exception. If you load the original system, select drop and click on editing (it might be working also when you load the planet directly). Edit what you want, but before you save the planet, change the planet version number (for droo, the latest is 2.4) one number up (2.4 -> 2.5), then save the planet. Oh and don't change the name or something, only the version. When you have done that all, you can exit the planet editor. The next time you load the sandbox, the planet should be the updated version (your version).
That way may be cause complications when the next official update comes, because of the version numbers, but I'm not sure.
The Ship from (imo) the best SciFi TV Show ever.
Thesaturnaerospace is right.
When editing a system, you have to click at the Central celestial Body, wich should be Juno. Then click the replace Button (the third one i guess). That should Open a window where you can select an other object from the list. If there are no objects in the list, you must activate the search filters by clicking at the 3-point Button.
Select your favorited Object and Juno should be replaced.
To add several planets to your system, again select the Central Object of your system, then click the add Button (that one with the + ) and select your Planet. To add another Planet you need to select the Sun again, then click add Body, and so on.
After adding a Planet you have to adjust the distance to your sun, because it is very far away from the Sun.
To add a moon to your Planet, select a Planet and click the add Button, the Rest is the Same.
I hope that helps a little bit, and sorry for the horrible english, but its not so easy, 22 years after finishing school 😁.
You can find such "Hidden" Structures very easy in the Planet Studio. You just have to load the actual Version (2.4 atm) of Droo and then look at the Tab where you can add Structures like Runways or Launchpads.
Stay Safe and good luck :-)
Yeah sometimes it is complicated to see where the booster is connected. What you can do is mirror the side interstage before you try to connect the booster. Then try to connect your booster, you will see If you are right when the booster also spawn at the mirrored side detatchers.
