yes but it takes a while

Yes It's normal

Nice that vimeo-videos was fixed.

Here's a puzzle that will be hard if you use video embedding though, just to give you an understanding on why I think video embedding should be turned off by default instead of on.

The endless scrolling is working as a whole it's not written page by page, it's written like giveaway based pages, table based pages, comment based pages etc.
The other reason the current settings system only handles on/off options i don't want to remake it yet.

I can't get other informations from the game without querying them one by one from the steam servers. I don't want to do that if you interested in similar features you can ask SG Game Tags' owner:

The colors doesn't make any sense, i made a color system (color heat, 0%-blue, 100%-red) before the 2.3 release but it was useless, almost everything was blue and you can't tell the difference between the shades so i removed it. It looks better in black
anyway it's not an important information like you have to check it before you enter or something like that, It's useful with filtering but nothing else.

I've tried some stuff and this is what I eventually settled upon:

Added this at the end of the chance block:

var ga_chance_style = Math.ceil(chance*10) ;

Changed the Display chances to this:

$(ga).find('.giveaway__columns').find("div:first").after('<div><i class="fa fa-fw fa-area-chart"></i> <span title="Odds: '+(entries/copies).toFixed(0)+':1" class="GA_chance_'+ga_chance_style+'">' + chance.toFixed(2) + '% chance</span></div>');

First try css sheet:

@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("www.steamgifts.com")
{
  .GA_chance_1
  {
    color:#663300;
  }
  .GA_chance_2
  {
    color:#cc3300;
  }
  .GA_chance_3
  {
    color:#e68a00;
  }
  .GA_chance_4
  {
    color:#99ccff;
  }
  .GA_chance_5
  {
    color:#3399ff;
  }
  .GA_chance_6
  {
    color:#0000ff;
  }
  .GA_chance_7
  {
    color:#99ff99;
  }
  .GA_chance_8
  {
    color:#4dff4d;
  }
  .GA_chance_9
  {
    color:#00ff00;
  }
  .GA_chance_10,
  .GA_chance_11,
  .GA_chance_12,
  .GA_chance_13
  {
    color:#ff00ff;
    font-weight: bold;
  }
}

Starting around version 2.3 when you introduced code to collapse the featured giveaways again, the button to expand them has been broken for me.
I've had a look into this and it seems like both your and the original code (v10) for the button are run.
The original code will expand the list and hide the button and yours will toggle the list again resulting in collapsed state.
This seems to be a result of a) your click handler being registered for document and b) their click handler registering after yours so it doesn't get removed when you recreate the button as it's not attached, yet, at that point.
Haven't been able to find a fix for it though :/

Links hidden in "spaces" isn't shown for embedded videos as can be seen in my puzzle.
You should take a look at the posts after the puzzle as well, there's a script for how to use embedded videos a bit more proper. So it doesn't embed them until you actually click it.

I don't know SG++
What this feature can do?

It's safe! don't worry about It :D

or
with filter

You can tell if you entered or not from the enter/Remove button's state. So it becomes unnecessary. If you disable this feature the fade effect will be re-enabled.
