With the advance of automation through share sheet, share has become one of the most used operations on iOS. Currently, share sheet is accessible with at least 2 button presses, i.e., tap to open and tap share button. Without opening a document, in the document list, we have to either “Edit, Select, Share” or “Swipe, More, Share”, which are a bit tedious.
I suggest adding “Share” in long press menu or in the swipe actions in the document list.
