[galaxy-commits] commit/galaxy-central: jgoecks: Trackster: support large (10, 000+) sets of chromosomes/contigs, as is often the case for lower coverage genomes. Subsets of chromosomes are loaded into in the chrom select and there are options to move to the previous/next set of chromosomes. If user enters chrom not loaded into navigation box, chrom is loaded and then navigation is performed.
