I would like to see the title area of dashboards compressed. Feels like there is a lot of wasted space. See image below for suggestion. An entire bar dedicated to a logo and search box is too much. Having the dashboard name and menus in the same space would help.
In general, current dashboard configuration makes it hard to get dense information on a page... which is often the purpose of a dashboard... lots of information but visually clear if well done. I am really looking forward to the dashboard enhancements announced at Engage 2023. More screen area! But even with that, IMHO, the way dashboards are set up lean towards a lot of white space. Buffers between widgets. Wide margins on widgets. Screen real estate is important.
