Datalife Engine - Türkçe Destek ( DLE )

Hello all,
I own some doubts about this module.

First Doubt:
I wanted to add to each movie page two buttons to mark the film as seen and schedule the same.
The module has the option to add these two buttons?

I found these buttons on a site that uses the same module.
Schedule Fiml Buttom: http://codepen.io/anon/pen/LNZaqb
Mark as Viewed Buttom: http://codepen.io/anon/pen/oxLVmB

I noticed that the two buttons use the same function of requests:
Requests: index.php?do=film-requests
Schedule Film: index.php?do=watchmovie
Mark as Viewed: index.php?do=watched


Second Doubt:
The module has the option to add waterflag on the movie images, but I wanted to add one more thing on top of that:

How can I do this?


Third Doubt:
How I can put buttoms to users can see the most famous movies, top rated, most viewed and also an option to choose a movie randomly?
The buttons I want to add are the following:


Fourth Doubt:
I noticed that this site movies have a button on top of the films:

HD Buttom
Clicking this button I'm redirected to a page which shows me all movies of this quality.
I think it is a tag, I noticed that the url of the site is as follows:
https://site.com/xfsearch/hd/
How it works and how to work with this xfsearch?
How can I add that kind of buttons on top of the films?
How do I add these types of tag to work with xfsearch?

Thank you,
I appreciate your help.
