Undo pop-up link disappears too fast and is too small

[Milkii Brewster]

Accidental swipe, takes time to notice what happened, and to tiredly move a shaking finger towards a small link, which very shortly disappears before the correct tap can be made.

Also, UI/UX wise, the area the undo action text provides on the screen is rather small, thus making it hard for some users to catch in time.
