Comparative genomics and synteny views (e.g. multiple JBrowse panes in the same page, relationships between genomes, Mauve-style ribbon views)
Structural rearrangement views (e.g. duplicated features or segments, Circos-style circular views)
Population genomics views (richer visualization of variants, population structure, haplotypes)
Graphical configuration and customization of tracks over the web (as opposed to editing JSON files)
Dynamic interactive filtering of track data (e.g. using slider or other controls to select subsets of features by score, length, etc)
Ability to upload, manage and delete new tracks via the web (as opposed to writing files on the server)
Integration with server applications and content frameworks (e.g. Galaxy, Chado, Tripal, Maker...)
Integration with client-side components to make web "dashboards" (alignment viewers, tree viewers, PDB viewers, ontology browsers, BioJS components, geographic maps)
General improvements to the user interface (e.g. resizing track heights, moving track labels, flip forward/reverse strands, subtracks)
Scalability (improved search; better handling of large track databases, large genomes, large numbers of reference sequences, multiple genomes, deep-coverage sequencing tracks)
More features for sharing and collaboration (Google Maps-style markup: ability to stick "pins" in the genome and share these overlays, commenting, chat, collaborative editing and annotation)
General improvements to the data back-end (understanding more file formats like CRAM, VCF4.2, more efficient bigbed/bigwig access)
More data of relevance to human genomics (e.g. a reference JBrowse instance with pre-loaded datasets for UCSC, ENCODE, HapMap, 1000 genomes, etc; easier cross-linking of model organisms to human orthologs/pathways)
Tools aimed at genome editing and bioengineering (e.g. CRISPR guide & primer design, confirming edits by resequencing)
Tools aimed at cancer informatics
