Numbers for clusters and white bar separation in plot_heatmap

[matasV99]

Hi,

Thank you for such a great tool - it allows visualization of lots of interesting metadata on a heatmap.

One slightly annoying feature is that it is sometimes difficult to differentiate columns between different clusters when there is a lot of them (10+ clusters). The default of plot_heatmap starts using continuous color palettes such as RdYlBu which makes it difficult to find where one cluster starts and another ends. Moreover, since there is no number at the top of the heatmap, I have to count the columns each time I am analyzing the columns in the middle of the heatmap.

Here is an example:

Solution:
Would it be possible to add additional parameters that allow for separation of clusters with a white/black line and numbering of clusters? I am attaching an example from DoHeatmap that has those features by default:

Alternatively: could you suggest how I could modify your code to make the ComplexHeatmap object have these features?

Regards,
Matas
