I found the dropdown menu list to be too long to be effectively used especially when viewed i chrome (browser) I can only see 5 genomes at a time and the ordering of the genomes isn't intuitive. 
Can I suggest that a frequently used genomes list be in the rest of the page so that it is easier to use for most users? like a table of common genomes to immediately create a new track browser from there? 

Cheers
Kevin
