I memeber Sh hatem talking about 3 thing that imam harawi talked about for improving khsuoo. hudoor was one of them I think?

You are thinking of a passage from Station 58: Tranquility (as-Sakīnah), where Imam al-Harawi describes the first level of tranquility:

"The tranquility of the submissive solemnity (khushūʿ) of service, performed with care, exaltation, and attentiveness" Day 64, 00:24:51. (سكينة الخشوع عند القيام بالخدمة: رعاية وتعظيما وحضورا)

So he said, "And as for the sakinah of dignity that he brought, that, that Allah subhanahu wa ta'ala brought down onto the, uh, its people, and made it a quality of theirs, it is the resultant light of the third sakinah that we just mentioned, and it is of three levels." … — Day 64, 00:24:51

Dr. Hatem explains that if you want to cultivate khushūʿ and attain tranquility in acts of service and worship (such as prayer, recitation, and remembrance), they must be performed through three things [Day 64, 00:24:51 – 00:27:28]:

1. Care (Riʿāyah): Giving proper care to the service—doing it right according to the Sunnah, perfecting your ablution (wuḍūʾ), having repose and calmness (ṭumaʾnīnah) in standing, bowing, and prostration, and reflecting on what you are doing Day 64, 00:24:51.
2. Exaltation (Taʿẓīm): Approaching the act out of reverent glorification, which stems directly from exalting the One being served—Allah (subḥānahu wa-taʿālā) Day 64, 00:26:22.

   Okay, and then to do it out of exaltation, ta'ziman, to do it out of exaltation. Exaltation of the service, and exaltation of the served, the one being served, Allah subhanahu wa ta'ala. … — Day 64, 00:26:22

3. Attentiveness / Presence (Ḥuḍūr): You were correct about ḥuḍūr! Dr. Hatem explains this as inviting your heart to the "feast" rather than just showing up with your body or your tongue. It requires consciousness, alertness, and keeping your mind awake. He points out that this attentiveness also involves watchfulness (murāqabah)—being conscious of Allah’s presence and His sight over you, rather than performing rituals or good deeds absentmindedly [Day 64, 00:26:22 – 00:27:28].
