Back Button Behavior in Plume Is Not Consistent

Does anyone else notice that there are times when pressing the Back button in Plume does not always take you back to the previous screen, but instead returns you to a different area of Plume, or skips the last few screens you have used?

It seems to happen when searching and following hashtags and viewing profiles. As most know, doing this can often cause you to become many steps away from where you were before you started following the links. Pressing the back button to return is the logical process for retracing your steps to get back to where you initially were but there are many times when pressing Back simply returns me to the timeline instead. At this point I need to retrace my steps to try to take me back through the path I was following, so I could go back and re-locate links, profiles, and hashtags that I wanted to look at. Which I WOULD have been able to look at if the Back button behavior actually took me BACK rather than dumping me back at the timeline.

It is hard to describe the chain of events that causes the behavior.... but perhaps some other users have noticed this as well?
