I'd like to ask you if there is a reason to capitalize all items in menus, etc in application user interface, for example
Why shouldn't I just label these items as File->Page setup etc.? This kind of capitalization just seems wrong to me - but I am not a native English speaker, so I just might not dig it.
In English, generally titles have all words capitalised except for conjunctions (of, for, and etc.) and prepositions (like with.) User interface elements (buttons, titles, menu items) are formatted like titles.
I have a piece of software I'm using right now which has a "Tasks" menu and 3 items as follows:
The difference in capitalisation on "new task" stands out a mile for me - it just doesn't look "correct."
