Thank you for your request. We are constantly working on creating a more comprehensive annotation source library.
We are in the process of updating our annotation track writer so that we can create new tracks more efficiently and quickly have them available from our data server. Once this is complete we will start updating our available tracks. I have added the tracks you mentioned to our list (Segmental Duplications is already available!) and we should begin working on them after the first of the year.
Additionally we are working on creating a tool that will allow the user to create their own annotation tracks from a variety of file types (GTF, FASTA, etc.), we will be implementing this tool in our analysis software SVS first but will then make it available in our stand-alone GenomeBrowse software.
Please let us know if you have any further requests or any questions.
