The Documents panel allows you to preview documents without opening them.
The panel shows documents from a directory (path) which is listed in the F12 - paths tab. The panel does not show documents that are located directly on the specified path. You need to create subgroups (directories) for each group of documents.
For example, if the path to the documents is "D:\drawings\", you need to create several subdirectories, e. g. "D:\drawings\Project1\", "D:\drawings\Project2\" etc. and place your drawings into them.
A document can be opened by clicking on the thumbnail of the document.
A right-click menu appears with the item create a similar document. If you often create similar documents, you can create a document as a template and then create documents as a copy of the template.
