Messaging system with discard user interface

1. A computer-implemented method of displaying a user interface, comprising:

displaying a preview of a message on a screen;

receiving a discard motion;

displaying a discard instruction that comprises a text message describing the discard instruction with varying opacity during the receiving, the opacity increasing in proportion to a range of the discard motion up to a first opacity until reaching a minimum motion threshold;

displaying the discard instruction at a second opacity greater than the first opacity once the minimum threshold is reached; and

discarding the message.

2. The method of claim 1 , wherein the discard motion is a swiping action.

3. The method of claim 1 , further comprising providing haptic feedback once the minimum motion threshold is reached.

4. The method of claim 1 , further comprising displaying a discard warning if the message includes creative tools, the creative tools including special effects.

5. The method of claim 1 , further comprising sliding the displayed preview along the screen in a direction of and in logarithmic proportion to the discard motion.

6. The method of claim 5 , wherein the direction is downwards and the discard motion is a finger moving downward on a screen.

7. The method of claim 1 , wherein the message is an ephemeral message having a time-limited duration.

8. The method of claim 1 , wherein the displayed message includes video.

9. The method of claim 1 , wherein the first opacity is 50% and the second opacity is 100%.

10. A non-transitory computer-readable medium storing instructions that, when executed by one or more computer processors of a client device, cause the client device to perform operations comprising:

displaying a preview of a message on a screen;

receiving a discard motion;

displaying a discard instruction that comprises a text message describing the discard instruction with varying opacity during the receiving, the opacity increasing in proportion to a range of the discard motion up to a first opacity until reaching a minimum motion threshold;

displaying the discard instruction at a second opacity greater than the first opacity once the minimum threshold is reached; and

discarding the message.

11. A client device, comprising:

one or more processors; and

one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the client device to perform operations comprising:

displaying a preview of a message on a screen;

receiving a discard motion;

displaying a discard instruction that comprises a text message describing the discard instruction with varying opacity during the receiving, the opacity increasing in proportion to a range of the discard motion up to a first opacity until reaching a minimum motion threshold;

displaying the discard instruction at a second opacity greater than the first opacity once the minimum threshold is reached; and

discarding the message.

12. The client device of claim 11 , wherein the discard motion is a swiping action.

13. The client device of claim 11 , wherein the operations further comprise providing haptic feedback once the minimum motion threshold is reached.

14. The client device of claim 11 , wherein the operations further comprise displaying a discard warning if the message includes creative tools, the creative tools including special effects.

15. The client device of claim 11 , wherein the operations further comprise sliding the displayed preview along the screen in a direction of and in logarithmic proportion to the discard motion.

16. The client device of claim 15 , wherein the direction is downwards and the discard motion is a finger moving downward on a screen.

17. The client device of claim 11 , wherein the message is an ephemeral message having a time-limited duration.

18. The client device of claim 11 , wherein the displayed message includes video.

19. The client device of claim 11 , wherein the first opacity is 50% and the second opacity is 100%.
