I'm not considering "my" playing style. I can't play the game, remember?
And it's not "forcing" anything. You can still technically keep one inventory per world.
(I know it's a hassle. But still, you
can do it).
And I understand that "most" games are designed so that your stuff stays in each individual world.
eg. Minecraft, Terraria, etc...
But also keep in mind that originally Junk Jack was limited in its World Sizes (thank you second-gen iPods

).
Meaning you couldn't (and still can't, really) get "everything" in one world. They're just too small.
However, for JJ2, I can defintely see Pixbits at least adding a "Keep Inventories Per World" option, for gaming-styles like yours.
But if they can't, then I hope you can come to terms with taking advantage with world-jumping, as Junk Jack is a game based around that feature, and you are only limiting yourself by not using it.
And again, it's not a feature that hinders the game. It's really just the way the game is.
PS. You can't consider everyone. If that were true, then people who
would want a world-jumping feature for Minecraft would get it. But they don't.
You can't please everyone, either. But you can try to broaden certain aspects to please as many as possible.
