Make “Edit” and “Approve” buttons visually distinct in medical notes

Affected users:
everybody

Task affected:
Editing and approving medical notes

Impact:
The Edit and Approve buttons look too similar.
This causes confusion and leads to notes being approved by mistake instead of edited.

Current state:
Both buttons have similar colors and visual weight.
Users can easily click Approve unintentionally when they meant to click Edit.

Competition consideration:
Many systems use clear visual distinctions (color, emphasis) between editing and approval actions to prevent errors.
