You used to be able to doubleclick/tap highlighted text to open popover menu in the document view (both on iPad and Mac). This was great, as it was a quick to add a title etc. Having to tap it once to open the context menu and then tapping the left most button is much more cumbersome. In Version 3.6.7, this is no longer possible, either by bug or by intention removal. If its a bug, please consider this a bug report. If you removed it intentionally (why?!), please add it back as an option.
