+\title{Add gene highlights to a ggtree object}
+\usage{
+gene_highlights(ggtree_obj, genes_to_highlight, hilight_extend = 18)
+}
+\arguments{
+\item{ggtree_obj}{A ggtree object to which the highlights will be added.}
+
+\item{genes_to_highlight}{A data frame containing genes and their corresponding colors.}
+
+\item{hilight_extend}{Integer, the extension of the highlight fan in degrees.}
+}
+\value{
+A ggtree object with added gene highlights.
+}
+\description{
+This function enhances a `ggtree` plot by adding highlights for specific genes. It adds both a semi-transparent fan-shaped
+highlight and a point at the node corresponding to each gene. Colors for each gene can be customized.
