Threads New Thread Sheet

When the user taps the compose button, the 'New thread' sheet slides up from the bottom of the screen, perfectly synchronized with the iOS keyboard. Within the composer, tapping the poll icon smoothly expands the input area to reveal poll options with a subtle fade and spring. Removing the poll collapses the space gracefully. Tapping the hashtag icon reveals a search input, and typing triggers a suggestion list that slides up from the keyboard. Finally, tapping the GIF icon transitions the view into a full-height GIF search picker, sliding up to replace the keyboard and composer layout.
