I added some loading lines, so that when we start to fetch, it shows the
lines, then when the fetch is done, we turn off the lines.
However, I have added a 500 ms delay to turning off the lines, so that each
time we are fetching, the user can see that something is happening at that
time.
I also muted the color since the movement all the time can be distracting.
