Much of the Zoho UI is excellent; sparse and orderly and I'm grateful for that!
No matter how large our monitors get, screen real estate is always at a premium and vertical space is especially precious.,
One of the great boons of "canvas" is the ability to use space even more parsimoniously.
Here is an example of wasted vertical space. "Yes", I know "icons" look nice but they are almost 100% void of content and, in this case, convey zero information and provide no value.
