(These are new features for Windows 7 which didn’t fit into the other categories. There are more Windows 7 features mentioned elsewhere; e.g. taskbar progress indicators and improved support for libraries.)
In Windows 7 you can now fully configure the Jump List attached to the Opus icon in the taskbar (and the shortcut icon in the Start menu). The Jump List page in Preferences lets you enable or disable the display of many elements in the Jump List, including favourites and recent folders, FTP sites, layouts, commands and shortcut folders.
Windows 7 removed the icon overlay that used to be shown for shared folders. Many people miss this feature and so Opus 10 now specifically checks for shared folders and manually displays the sharing overlay for them. (You can disable this if you wish.)
Opus 10 is flagged ‘DPI Aware’ so that, on high-DPI machines, Windows 7 will not scale and blur its windows and so that Windows 7 does not make drag & drop behave erratically. (If you have a high-DPI machine but had not noticed this, note that it only happened sometimes due to a bug in Windows 7.) As on normal-DPI machines, font and icon sizes are still up to you and can be configured via the Preferences and Customize windows.
Glass status-bars (if enabled) now remain glass when their windows are maximized.
When changing the desktop wallpaper, Windows 7’s fit and fill modes are now supported.
There is support for the new shell:-style shortcuts of Windows 7 (e.g. shell:VideosLibrary to go to the Videos library, etc.).
Static folder commands are now supported, so for example, the Create New Virtual Machine command will be displayed when you browse to the Virtual Machines folder). These commands are shown on the Toolbar using the existing Marker TOOLBAR command.
Static cascading context menus are now supported, so programs which add their context menus using this new method (e.g. PeaZip) will work properly in Opus.
