 ### Added
 - Added a image data download speed indicator to the statusbar. On hover a tooltip is shown that show the total amount of downloaded shard data. [#6269](https://github.com/scalableminds/webknossos/pull/6269)
 - Added a warning for when the resolution in the XY viewport on z=1-downsampled datasets becomes too low, explaining the problem and how to mitigate it. [#6255](https://github.com/scalableminds/webknossos/pull/6255)
+- Provide a UI to download/export a dataset in view-mode. The UI explains how to access the data with the python library. [#6283](https://github.com/scalableminds/webknossos/pull/6283)
 - Added the possibility to view and download older versions of read-only annotations. [#6274](https://github.com/scalableminds/webknossos/pull/6274)
