User Interface
Papermerge user interface is designed to be very intuitive. However, it is a good idea to know major interface areas by their name because they are referenced many times in this manual.

Figure 1. Main user interface elements
Document Browser
In Figure 1. marked with number 1.
Document browser is designed to have similar look and feel of modern desktop file browsers. This is the place where you browse your documents and folders. The huge different between Papermerge’s Document Browser and usual desktop environment’s file managers (e.g. Windows File Manager) is that in Papermerge there are only two times of items - folders and documents. Documents are mainly PDF, jpeg, png and tiff file formats. There is no such thing as audio files or video files.
Right Side Widgets Panel
In Figure 1. marked with number 2.
Details of selected folder or document appear in so called Right Side Widgets Panel or simply Widgets Panel. There may be many different widgets, but three most important ones are:
OCR Language Widget
Info Widget
Metadata Widget

Figure 2. Right Side Panel’s Widgets display additional information about selected documents or folders.
OCR Language Widget will always be displayed (when in Document Browser). OCR language indicates in which language your documents will be OCRed.
Basic Info Widget displays basic information about currently selected document or folder. Among basic information like title, owner and creation date, it will display folder or document’s associated tags. In Info Widget there is (an extra obvious) download button. Note that with download button in Info Widget you will download only latest version of selected document (or folder content). In order to download older versions of the document you need to open document in document viewer.
Metadata Widget will display metadata of the currently selected folder or document.
Display Mode
In Figure 1 marked with number 6.
With display mode drop down menu you can switch between different modes in which folders and documents will be displayed in Document Browser. Currently two display modes are supported:
list
grid
Besides obvious visual difference there is one very important distinction between two display modes: Metacolumns are displayed only in list mode.
