The top menu bar is great for navigating in your dashboard, but there’s so much unused screen real estate.
The most useful would just to be able to add a clock on the top right (without using plugins).
Next it would be great to be able to add status icons on top.
For example, I have an icon that lights up when my mailbox is opened, but you could also add icons that change color when the washer or dryer is finished. When clickable you could show a popup that gives more info on these devices.
Right now this all takes up a lot of space in the main dashboard that could be used with more useful information.
