I just installed the Android app, and my very first impression is I can't find the instructions.

OK. (But perhaps do like the Flightradar24 app, remembering the previous zoom through thick and thin (all manner of restarts, powerdowns, etc.)

On Twitter, "?" brings up a list of keyboard shortcuts. Saves a lot of bytes,

• Visit https://www.windy.com/-Rain-thunder-rain?rain,23.790,120.624,8
• Hit keyboard→→→→... to advance time three hours at a time.

You will observe that for major storm blobs one can follow the logic of how they travel.

But for anything less, it is: how did cloud A jump to point B? Etc.

Therefore we see that three hour jumps are just too wide.

One hour jumps are needed to keep the cloud movement logic recognizable. P.S., no I am not "overly zoomed in for my own good."

The site does a super job with the little wind arrows. Now time to fix up jerky weather blob (cloud) movement.

In fact I now notice the original "pizza pie" in the image indeed has eight slices, apparently trying to express the same thing
(that a slice pointing north is called "S"(outh), etc.)

@Gkikas-LGPZ I see. Hmmm, it seems that their predictions are vastly different too. So I suppose you fellows made the best choice for default. OK.

In the app go to settings. Now look at temperature rain snow excetera. Some of them have the metric units on the right, and some of them on the left. They all should be on the same side. The English units should be on the other side.

Perhaps have it instead use an arrow, just like I drew.

This border is barely visible:

We need to see it in order to know what the current time of the frame is.

@Yves70 That's too bad. Each time I start up I have to zoom in thousands of miles. I guess whoever set the defaults lives in a larger country or uses some regional approach to looking at weather. Alas, there is no "one size fits all."

@jidanni I want it to go to that same zoom level every time I start the app.

How to change the default startup zoom level in the Android app?

I found how to change the default startup location, but not the zoom level.

Ah, perhaps simply a case of https://en.wikipedia.org/wiki/Cultural_bias ,
where the author A sees a non moving image of the animal on the right,
to mean "faster" than the moving image of the center animal.
Different than viewer B living in different country C.

@Korina Yes. I was going to say that the middle animal certainly looks like it is much faster than the animal to the right. However before saying so, I though I should have a closer look to see which animals they actually were.

@BrandonKing No I never did find where the three animals appear in my browser from.

I am debugging the three running animal images (upper right in the image below. Middle one (selected) with brown oval) but I cannot find where they are stored.
Here I am in Developer tools, looking at iconfont, but it doesn't contain the three running animals. Can't find them anywhere else in the Network tab either. Yes, I read tip.

I got a message calling me stupid, for pressing a like button.

OK now I know.
