The GUI has inconsistent capitalization between various buttons, menu titles, and text descriptions.

One thing not listed: the statistics. All of them have all words capitalized, except for (including the 1.8.2-pre1 ones):

• Games quit
• Note Blocks played
• Note Blocks tuned
• Plants potted

The statistics can't be translated (see MC-46341 and MC-77880). And while checking for non-translatable strings, I found out that the spectator commands (that also can't be translated) also have some inconsistencies, like "Close menu" and "Next Page".

Also, if you try to open a world that was last loaded in a newer version, the game will display a confirmation screen. The button to confirm is labeled "Use anyway", where this last word should be capitalized.

Also, "Auto-jump".
