In Vista and Windows 7, Opus now makes use of the advanced features of the Desktop Window Manager to provide subtle transition animations when changing directories, opening / closing Lister panels, changing pages in Preferences, etc. You can fully configure the transition animations in Preferences.
For a more modern appearance, the File Display, Folder Tree and Breadcrumbs control are now themed under Vista and Windows 7. Lister menus now use the standard theme on Vista and Windows 7 (provided the toolbar style is set to Standard and not Office 2003). Additionally, all list and tree controls throughout the program (including all Preferences pages) are fully themed.
Folder tab background colors now work even if the tabs are themed. (Theme elements are re-colored on-the-fly.)
Folder tabs can now have ‘normal-sized’ close buttons. (You can still have small ones or turn them off entirely if you prefer.)
When dragging and dropping it is now far more obvious which item is under the mouse (the target item is now highlighted rather than simply being outlined).
The general appearance of the Lister has been improved with new anti-aliased button glyphs, more subtle gradient fills and the elimination of duplicate/unnecessary frames around Lister elements.
The frames and headings around Lister elements can now have their fonts and colors configured if you wish to override the system-wide settings.
