Need help about samsung widgets!

[Guest windowsrb]

Samsung's UI Touchwiz looks good.

I'm now using Mobile shell but i would like to know more about widgets:

1. i have 6.1 ROM and am i limited only to these few widgets (about 10) on first screen?

2. How to download additional widgets like on s5230 (hundreds of them can be added from settings and more from the internet)...

3. Is there any chance to use free connections when updating samsung's widgets (like weather or news updating) like mobile shell or other programs can do.
