> Why it is not possible to add the examples? Is there any technical problem or just lack of time?

Do you mean a link to open the desktop app? I guess I could try, but I think it's easy enough to find the example manually. There's also some technical issues with it.

> I din't notice that the online version has less features.

I guess the line "The desktop version [2.0.1] is much faster and has many more features as well as additional examples" wasn't clear enough. I'll see about improving it.

> When it shows the current, all of them have the same length.

I think I'll add an option to make the arrow length vary. I'll also add a gamma slider.
