Suggestion 1: make it more clear that the post is not complete
This is really minor, but a test user of my community site indicated that it was not clear to him that posts with a '+' button (see screenshot below for an example) were truncated. Suggested fix: add '...' at the end of the displayed text or some other truncation indicator.
Suggestion 2: make the post open at top rather than bottom when tapping '+'
This is a more important issue. The same user also noticed that when the little plus sign is clicked to expand a post:
... then the post opens at the very bottom (showing the 'enjoying the read?' box) rather than the top of the post:
We think it would be more intuitive if pressing the '+' would either make the text expand without opening the post or to open the post at the top. Hopefully this can be changed. Thanks!
