Highlight Wishlisted Games Feature

You need to install the ESGST addon (don't use the script, it can be slower than the addon).
Once installed, go to your SteamGifts profile, and at the bottom of the left side menu you should see a section for ESGST. Click on settings, there are a lot of options you can set, but I recommend you enable these:

9.9 Early Access
9.10 Followed
9.16 Ignored
9.22 Owned
9.24 Package
9.29 Removed
9.33 Wishlisted

You can click on each item to get a panel on the right side with some basic information on that item and sometimes more options for customization.
Next go to sync, under section 1, select (at a minimum): Owned/Wishlisted/Ignored Games
Under section 2 you need to set a frequency (in days) for each option that you selected in section 1.
After that do a manual sync to get the ball rolling.

ESGST can help you. It has a ton of useful features. After installing the extension i recommend going through the wizard and enable most if not all of what it recommends to enable.
