Logos Bible Software has provided a helpful current webinar about how to get started with Logos 7.
As of v. 7.8, Logos Bible Software supports reopening closed tabs both via panel menus and keyboard shortcuts (PC: Ctrl + Shift + T, Mac: Cmd + Shift + T). Conveniently at least for PC users—and I suspect also for Mac (?), the keyboard shortcut is the same one that will revive tabs in major browsers like Google Chrome.
For additional details and a walk through of how to access this feature through the panel menu see the LogosTalk blog.
at this point notes and highlights from the web app will not show up in the desktop app and vice versa. We’re working on creating this cross-platform syncing, but meanwhile you’re data, notes, and highlights are completely safe. Just keep in mind that as we make the transition to a new note system, you won’t be able to access your notes across all platforms.
For more about the new web app, see the original post on the LogosTalk blog.
