Filter on "Giveaways Created"

I use the user page for that. If you do a text search for "Awaiing" (as in "Awaiting feedback"), you can easily find the giveaways without feedback. Don't forget the ones with multiple copies (they won't have the "Awaiting feedback" text I think), you could search for "Copies" for these ones.

I guess most users wouldn't need the feature, but it could be very handy for the users with lots of giveaways.

In your case, these don't seem to have any feedback (I searched back about 2 weeks):
https://www.steamgifts.com/giveaway/Dj62r/dale-hardshovel-hd
https://www.steamgifts.com/giveaway/cfxoh/spirit-of-war
https://www.steamgifts.com/giveaway/AmxXe/galactic-inheritors
https://www.steamgifts.com/giveaway/ovySU/warriors-wrath

All of them are in this week. Just open https://www.steamgifts.com/giveaways/created and you see which are still awaiting feedback.
