I just saw the merged sandbox, and woah...
I notice that in the OP post that the active challenge is classified into 3.
Will it be wise if we make 3 sandbox? One sandbox for each type? So we have One sandbox full of KOTH. One sandbox full of codegolf and one sandbox for others (popularity, puzzle, troll, etc).
15 pages of sandbox is a little bit, intimidating for me. Classification may help.
Although I understand that it can be intimidating at first glance, this can be much improved by sorting by "active" and I think that is sufficient. I believe there is much more benefit to keeping a single unified sandbox than there would be from splitting it.
If someone wants to drop in to the sandbox and give some quick feedback, they are going to drop in to just one of the 3 sandboxes, give feedback on a few posts until they find they've run out of time, and then neglect the other two sandboxes, even though that was never their intention. Keeping it together means that what is prioritised is what has been recently updated, not one challenge type over another.
Also, people who are unfamiliar with a given challenge type may still have useful feedback, which they will give if they see the challenge on the list, but might never see if they don't feel the other sandbox is their place. So it's better for everyone, whether they are interested in all challenge types or just one or two.
The site and community benefit from more people, and more questions. I want everyone to be encouraged to ask any kind of question, and for everyone to see the kinds of questions they don't ask themselves. This way there are more ideas shared and a code golf may be inspired by a King of the Hill challenge, or a King of the Hill may be inspired by a fastest code challenge. This way a sandbox post that turns out to be unsuitable can still be scavenged for spare parts so that we get more questions overall.
I'm against anything that makes the community more divided, even indirectly.
