[Feature Request]: Improve the visual feedback of the last task result

[Weyaaron]

Problem statement

The current ui does a poor job of clearly communicating the result of the last task. This should be improved, not least to decrease the reliance on audio-feedback(See #32 for a discussion on this in particular)

Solution

Maybe some combination of the following:

• Flash/lock the screen/the result
• Clearly describe it using text
