When opening a text “cell” in the Detail view, it should be expandable to take up the entire, or almost the entire, screen. Currently, it leaves quite a large frame which eats into the useful space.
For example, I use these for meeting notes during screenshares and I figured out a custom trick (edit the HTML myself using Chrome’s Inspect tool) to get this to a better size for using for meeting notes. It would be nice to not have to do this every time though, and there are probably plenty of users who don’t know how to manually edit HTML and CSS.
The current sizing leaves borders that are unnecessarily big for this purpose and reduce the amount of precious useful space on the screen.
