The Circular Viewer plugin provides the capability to show the circular view of a nucleotide sequence.

If you work with a file with many sequences the button closes circular views if some circular views are opened and if all circullar circular views are closed, it opens all of them.
Also, you can mark sequences as circular in UGENE by the Mark as circular sequence context menu item. When the sequences are marked as Circular, the Circular View is automatically opened for them in all opened Sequence View windows.

The Circular Viewer is has opened automatically when the Sequence View is opened for a plasmid.
The inner-circle represents the sequence clockwise and the scale marks show the corresponding sequence positions. The sequence annotations are represented as curved colored regions at the outer side of the circle.
The Circular Viewer helps to navigate within the sequence. You can select an annotation on the circular view and the annotation will also be focused and highlighted in all Sequence View areas: Sequence overview, Sequence zoom view, Sequence details view, and Annotations editor.
You can also select a sequence region:
It is possible to rotate the circular view using the mouse wheel. Also, it is possible to shift the start point of a circular molecule by Edit sequence -> Set new sequence origin context menu item.
Here you can browse for the file name, and select the width, height, and resolution of the image as well as its format: svgSVG, psBMP, pdfJPG, bmpPNG, jpegPDF, jpg, png, ppm, tif or tiffPS, and TIFF. Also, you can include position and selection markers to in the image by the corresponding checkboxes.
