Capitalizing texts in user interface

Question

I\'d like to ask you if there is a reason to capitalize all items in menus, etc in application user interface, for example

• File->Page Setup
• Edit->Select

Answer 1

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:

• New task
• Delete Task
• Task Properties

The difference in capitalisation on "new task" stands out a mile for me - it just doesn't look "correct."
