Office 365 Excel ribbon design is a catastrophe
The current Office 365 Excel (Mac) ribbon design should be 'revised' to previous versions. The font and icon sizes and styles are very difficult to read, especially for people with bifocals or altered vision. E.g., the 'Fill Color' icon used to look like a paint can and now appears as a faint tin can. Font sizes are too small, thin, faint. Just because you can change something does not necessarily make it better. Perhaps Office designers should be required to read Don Norman's design books.
