The native UI is designed to imitate the functionality of native applications, such as with the use of grayed-out buttons to indicate non-interactivity and the ellipses … suffix to indicate that clicking a button will open an additional menu.
On the web UI, buttons for upload and download are grouped with blue boxes. "Submit" actions are indicated with a high-contrast green, while secondary actions needed before the submit action are colored in lower contrast blue. Interactive elements are shown with a drop shadow, and focus (for keyboard interaction) is indicated with a dotted border. All colors are chosen for at least 3:1 contrast with their backgrounds. The two groups are designed symmetrically to simplify user effort.
