What does your feature entail? What is it for? How will it affect existing workflows or user experience?
Being able to d&d tabs between tab groups in the sidebar.
I quite like safaris behaviour of letting you "unfold" your tab-groups which makes changing the sidebar view from "windows" to "tabs" obsolete (which currently (2023-10-26) ist not working completely as desired I would say, see here) and also lets you drag and drob tabs between different tab groups. This makes it easy for me to rearrange my different tab groups, representing different tasks, topics or researches where I might discover something in tab group A that later on is better to be in tab group B.
Anyways, great work you did so far with Orion!
