Wish: improve Animate Slider defaults

I’m using the animate slider option a lot to create images for animations / videos.
I have a Rhino button which creates a floating viewport with the size of 1600 x 900 pixels and another one for a portrait floating viewport which looks good on a phone screen.

One thing which really annoys me is that I always have to select the viewport.

Let’s say I change the viewport from what is set by default to Floating, close the menu to change the view angle and open the menu again, the viewport is by default again the main viewport in my Rhino.

@DavidRutten I think it would make more sense to use the current viewport as default.

A second improvement could be that Grasshopper automatically defaults the Frame count to the range of the slider +1. I think this is the most common use case and it would be one thing les to think about.
