Please track last app(s) watched

RE: Please track last app(s) watched 

SITUATION:

I appreciate it that Roku is now requiring Roku app providers to include  "Keep Watching" and "Last Watched" (watch history) features pertainining to content within each app.

COMPLICATION:

Those within-app features don't, however, help viewers remember which app(s) they last watched. 

REQUESTED RESOLUTION:

It would be extremely useful if the Roku OS would add "Keep Watching" & "Last Watched" (watch history) features pertainining to last app(s) watched. We Roku viewers who watch content on multiple Roku apps would greatly appreciate it.
