The interface looks familiar, so users shouldn’t experience any navigation issues. Opening a drawing can be done using the file browser only since the drag-and-drop feature is not supported.
As far as preferences are concerned, you can specify the initial viewing mode for DXF and DWG files (e.g. zoom drawing to fit, last saved) and raster (e.g. initial rotation for BMP and JPG).
In addition, you can establish the printer initial page orientation, raster images in drawings options (e.g. ignore always), and Xrefs in drawings (e.g. browse if not found), as well as enable confirmation on quit and hide menus from the main application window.
