I'm coming from Arc and loved the ability to have different "Spaces" for different Intentions. For ex. I have a "Media" Space for consuming Videos and Articles, and a "Personal" and "Business" Space for corresponding Tabs. Whenever I need to switch focus, I just swipe left and right on the vertical tab bar between these "Spaces". Something similar could be achieved using Tab Windows in Orion.
Atm you need to click on the Window Picker:

If we add a swipe gesture for this, it would improve the UX. For comparison, here is how it is implemented UI-wise in Arc:

Each "Tab Window" is shown as an Icon and you can quickly add one with the plus button. You can then determine, what profile the tab window (or "Space") should use as it's base and therefore the usability of both Tab Windows and the profile feature of Orion becomes more convenient.
