Drag & drop of tracks is supported in UTGB, and also you can resize the height of tracks by dragging the lower frame border of the tracks.
The following keyboard shortcuts are provided for relocating the window location quickly:

Tracks displayed in UTGB can be configured by editing config/view/default-view.silk file. Each track configuration enclosed in track node has common parameters, class, name, pack and height. The class parameter must be present to specify a type of the track. Here is an example of a track configuration:
-track # Track types. (e.g., ReadTrack, WigTrack, RefSeqTrack, RulerTrack, etc.) # Case differences and spacing will be ignored in this parameter. -class: ReadTrack # Name of the track -name: BED Track # To pack track height. If pack value is true (default), the height of this track will be fit to its content height -pack: true # Pixel height of the track. If pack is set to true, this field will be ignored. -height: 30 # Track-specific properties. See the track catalog for details -property -path: (read file name)
The other parameters are optional but tracks usually have track-specific configuration parameters. For example, ReadTrack requires path value under property node to specify a data source to display. For details, see Track Catalog.
To set the default coordinate location in genome to display, use track group:
-track group -coordinate -species: human -ref: hg19 -chr: chr1 -start: 1 -end: 10000
In UTGB, you can display data written in BED, SAM, BAM, WIG, FASTA format data. See the following page to create tracks for these data formats.
These documents are for programmers who want to develop your own tracks.
