Navigation Lock has been improved and now works with any type of folder change, rather than just double-click / parent / back like in Opus 9.
When the two file displays go out of sync the new non-modal warning system is used to alert the user of this, rather than the old method of flashing the title bars.
A new option has been added to automatically select the folder you were in when you go up a level.
An option to display a .. parent item at the top of each folder has been added. Double-clicking this item will take you to the parent folder (equivalent to clicking the Go Up button). You can also drag and drop to this item to copy/move files to the parent folder. There is an additional option to hide the .. item when the file list is grouped, as having the .. item appear in a group may be undesirable.
The menus generated by the Go FOLDERCONTENT command now have a new selection method by default. With the new method, sub-menus will auto-expand when the mouse hovers over them – if you click an item that generates a sub-menu, it will select the actual item rather than opening the sub-menu.
The FOLDERCONTENT argument can take the new dblclickmenu parameter which changes this behaviour to expand on both hover and single-click, and select on double-click. The nomenusel parameter reverts to the Opus 9 behaviour of expand on hover and single-click, with no selection possible of sub-menu items unless the button argument is also specified.
Items listed in Folder Content menus now display context menus when you right-click them – this behaviour can be disabled if desired using the new nocontext argument.
There are new sortext, sortdate, sortsize and sortreverse parameters for the FOLDERCONTENT argument to control sorting, and the hideext parameter can be used to hide file extensions.
Finally, the new copy and move parameters let you create Folder Content buttons that copy or move files into the selected folder.
The Prevent automatic loading Preferences option has additional options to control which types of folders will not be loaded automatically (e.g. when Opus first runs, or a Lister Layout is opened). Enhancements in Opus have improved the performance of this system and therefore setting this for network drives in particular can result in dramatically increased Lister performance when using slow networks. Note that the new non-modal warning system is now used to inform you that a folder was not loaded, and gives you the option of reading it and of editing the Preferences settings.
