Heatmap needs to be a bit darker/lighter

It’s great that Sharesight guys have introduced a heatmap function. Must have been a shipload of work. However I find the colour variations are not refined enough. eg holdings with big increases are too light green and ones that have gone down a lot are not dark red enough. We need something like what you get on to the finviz site where the colours have more gradation. Can’t really tell what’s gone up significantly and down significantly.
