Better Explanation: On Java if you hold a Key before leaving the inventory, it will trigger when you leave (For example holding forward(w)) This inconsistency has constantly bugged me and many other players who had played Java extensively.
I believe this is intentional according to the Build 9 change log:
Tweaked the UI in the settings screen
In fact I feel that the biggest complaint about the ui is it being too small, stretching the Settings menu makes it better.
I would like this issue to be reviewed as I have recently done in-game tests with the /testfor command. The results conclude that this bug is an issue.
Yes, I have been testing this and it still is effected on 0.17.0.2
1.7.2
I can confirm that while custom skin packs show up again in the latest beta (1.14.0.2 BETA), they don't remain applied on game restart. Not to mention that nowhere in storage has a "skin packs" section to allow us to remove the skin packs.
