Regarding multi-language fields such as TextLanguage, TextareaLanguage, and PageTitleLanguage:
When multi-language fields are shown in Page Edit mode, I often use them next to non-multi-language fields. That makes the page appear a bit disorganized and cluttered because multi-language fields vs non-multi-language fields don't align horizontally. The reason is that multi-language field have "language switcher tabs" that forces the field to "jump down" whereas normal fields stay in the normal position. See screenshot 1. It makes me sea sick! ?
Suggested solution is to move the "language switcher tabs" up so that it aligns with the field label. See screenshot 2.
