Free version only shows how work component.
1) Seems, problem in Slider. It has conflict with SEF Translate component.
We can configure PRO version and make it comfortable with your website.
2. No, link will have below look if you choose Redirect method. If you select Redirect then your website will be redirected and page will be opened on selected language.
3. FREE version has Instant / jQuery / Redirect (with Google Frame) translation methods.
If you buy PRO or PRO Commercial you will get Redirect without Google Frame and for edit translated pages
and translated URLs you need PRO Commercial, not PRO.
