Components
The Acrylic Paint is a coloring tool used for making some drawings and also to paint as users pleases. Users have the ability to change the color of drawing/painting to whatever color they desire.
Proposal
Whilst making a painting, I made a delicate mistake, that I had to draw across my original work.
(see photo below)
I searched for a way to undo my last error, it wasn't available in the App. All I could see was the eraser option. Of course we know that the eraser cannot completely wipe out error on some delicate areas. And while trying to be careful, I wiped of my original drawing. It really got me heart broken. So I am using this medium to propose that the App should have the 'undo and redo button'.
Mockups/Examples
Well there's a similar app that do almost what the Acrylic paint does. The app is called 'draw'
The app draws too, and have the undo and redo button.
(see photo below)
From the photo above, we can see that there was an error across my drawing. Which led me to use the undo button, which is above the painting (the curved arrow sign)
See result of the undo button below
From the photo above, we can see that the last actions were removed and thereby making my drawing to be in the form I want it to be....
Whilst I was enjoying the undo button, I used it carelessly that I had to temper with my actual drawings and got some art removed
(see photo below)
from the above photo, you can see that the hair strands aren't complete because I carelessly used the undo button on it.... Now here's when the redo button came into use. I had to use the redo button to get it back.
(see photo below)
We can see from the photo above that the drawing is done. The exact way I drew it to be....
From the aforementioned examples, I think the developers of the Acrylic paint App should consider the undo and redo button to existence.
When it is added, the app will be perfect and very easy to use without been cautious of any error.
Benefits
With this new feature, users would be less cautious.
The App willd be perfect.
Users will be able to adjust their errors, either to undo their previous action or to redo it.
