+# Mango's Vision

-Scroller Layout
+**Mango's primary goal is stability**: After months of testing and development—and aside from a few lingering GPU compatibility issues—it should now be stable enough. I don't plan on making many breaking changes.

+**Mango's preference is practicality**: I tend to add features that genuinely help with daily workflows—things that make our work more convenient.

+**Mango won't cater to every user preference**: For niche feature requests, I'll take a wait-and-see approach. I'll only consider adding them if they get a significant number of upvotes.
