> Five buttons, all for spaces? That would already be a sign to me that whoever designed that UI wasn't really thinking straight...
It's a sign to me that they're extremely lazy, or their code is so bad that making small exceptions are very difficult/brittle.
"Now that we're translating this UI to English, what do we do with all these buttons that aren't needed?" "Too much work trapping into the UI drawing code to hide them, let's just remap them to something else... how about space! That's harmless!"
