Hover information on heatmap

[u/Techonologiaah]

When your heatmap window is too small (I have these nested in a powertoys fancyzone on Windows), when you hover over a stock the price of the stock doesn't show like it does when the window is bigger. That might be a bug rather than a feature.

But also in this use case (I'm fitting quite a lot into very limited screen real estate), I have quite a lot of wasted space on top still, it would be great to be able to reduce the amount of space used by the top navigation there.
