This is the place to provide feedback about any little thing that you find annoying, even though it may not rise to the level of an outright bug, and may not require the addition of a new feature.
We don’t necessarily want to hear about everything you would do differently if you were writing the app from scratch. Keep in mind that not everyone wants everything the same way, and we certainly can’t please everyone.
On the other hand, if you find something about the app that bothers you repeatedly, and that seems to be perversely annoying for no apparent good reason, then feel free to sound off about it here.
