Cursor in next row for hashtag-filter in mentions-textfield is great.
But the text field has no more auto-height. The height is fixed. And the text scrolls up over the hashtag.
By the way, an additional class for hashtag in mentions would be good. This could give the text field a min-height for mentions with hashtag (52px). And a min-height without hashtag (36px).
Would improve the look of the story-textbox.
So, and now I enjoy my weekend.
