"Back" button in Tagging goes grey#252

I’ve had a few situations where the “back” button in the Navigation pane goes grey (and therefore, cannot be clicked) when I’m tagging. And other times it’s available to go back and forth. Any rhyme/reason to this behavior? I could understand if you can’t go back if the study is marked “Complete”, but that doesn’t seem to be the case. It would be useful to be able to go back to see a previous study or add a tag I forgot to mark without having to try to remember what that study was and try to find it in Study Inspector (which has happened to me)…

“Back” is scoped only within a “session” of screening/tagging/extraction.

If you navigate away from e.g. the screening page e.g. to edit your protocol, your screening “session” has ended. When you return to screening, the Back button will be disabled because there’s no history of studies screened in your current session.

We implemented this way for:

• Technical simplicity
• Product simplicity. One dilemma to consider: when the user has changed “sessions”, should Back send the user to only studies they screened, or all studies screened by anyone in the nest, in order. Users may consider either of these expected.
  • I know you’re not using NK collaboratively (at least yet), but this is a consideration for other users.
• Perceived futility of using back navigation in this fashion. Going beyond a few studies back gets really clunky, and we imagine that going back a few studies will typically be done in the same session.

However, I totally see the use case you’re pointing out. You’re tagging, modify the tagging hierarchy for 30s, then return to tagging but realize you need to touch up a study from 5 mins ago with new tags. Perhaps you’re imagining a “session” should be extended (e.g. to as long as you’re in AutoLit for a given nest)?

Got it - thanks for the clarification. I totally get that it’s a bit of a different ballgame with collaboration. Your idea of extending a “session” is a cool idea!

To be honest, I hadn’t yet tried to use Back after leaving the Sequential screens and then returning! I think it has value for bookmarking your ‘spot’, so I support longer ‘sessions’ for that. I know we have to balance that against locking other users out of the study in question, but something like a 5-10 min time-out (regardless of whether the user left the screen). Thanks!
