Highlight specific gene(s)

[ValWood]

It would be really nice if we could highlight a specific gene (or genes) in a model.
For example, to highlight the gene of interest when embedding in a gene page as at Alliance, or PomBase
https://www.pombase.org/gene/SPAC1834.02

It is sometimes quit difficult to locate the gene of interest in larger models

This is something that would be useful to UniProt too. When viewing a GO-CAM within a UniProtKB entry page it would be helpful if we could pass to the viz a node in the graph to highlight, which would correspond that UniProtKB entry.
