Attached is a screenshot of the View menu.
I cannot access the sidebar import function by the keystroke command-option-3 because it is assigned the same one as for the reading list and the latter is getting priority.
BTW - now fully operating on DEVONthink 3 and enjoy the interface and new functionality.!
It’s possible to set things straight using System Preferences > Keyboard > Shortcuts > App Shortcuts, add a section for DEVONthink 3, and then add a shortcut for Import assigning ⌥⌘3 to it, and a shortcut for Extras assigning ⌥⌘4 to it.
Cheers, thanks for the confirmation and tip Korm.
Thanks for the bug report, the next release will fix this.
