STDU Viewer 1.6.350.0


STDU Viewer 1.6.350.0 comes with a very well-organized tabbed interface. It is divided into two panes. The first one to the left enables you to get a quick preview of the file content, bookmarks, thumbnails, highlights, access a search functionality or just explore the entire file system. To the right you will see the entire content of the opened file. You can change its layout in order to “page”, “face” and “face, separate first page”. Each opened file appears in a different tab. You can have a quick overview using the “Show thumbnails” button in the top-right corner of the main window. You are able to choose a tab theme as well.
