This is a small bug. When I am using this forum and typing I notice the feature of a popup blue window offering similar posts. This is great. However, the "Paperpile" banner which is either at TOF on scroll or which starts vertically offset on the page is at top layer level. This means it is on top of this useful popup. The blue box is also on top of the right hand menu in portrait (see comment below)
Suggested: raise blue popup to second top level (z=1). Change other menu bar (Home, Features) to top most level (z=0). Move paperpile graphic bar (with magnifying glass etc) to z=2 level. I suggest this order for portrait or mobile phone screen issues.
Thanks again for this great app!!
