Your idea.

It is necessary to implement the preview of documents or files. both in icons and in the preview pane

and here too, make it possible to preview the documents

examples

LibreOffice Openoffice Microsoft Office etc etc all create embedded thumbnails/previews for office files they create. ONLYOFFICE doesn't appear to :(

KDE desktop environment has thumbnails preview for most of the popular file formats to be shown in its file manager, Dolphin. Including .docx, .pptx, .xlsx, .pdf etc. And the libraries are for QT, which the OnlyOffice DesktopEditor uses. So it shouldn't be a problem to use these libraries to generate thumbnail for supported file types of OnlyOffice.

Links to source of the libraries used to generate thumbnails: Includes office file preview - https://invent.kde.org/network/kio-extras/-/tree/master/thumbnail Includes PDF file preview - https://invent.kde.org/graphics/kdegraphics-thumbnailers

Other PDF file preview libraries:

1. Microsoft PowerToys File Explorer add-ons
2. SumatraPDF Reader

While EPUB file is associated with OnlyOffice, it doesn't show EPUB icon, instead shows OnlyOffice icon. Also, with file preview enabled (I use other software to enable file preview) PDF & EPUB both doesn't show their file ext icon. EPUB shows nothing and PDF shows OnlyOffice icon.
