Problem Statement

i cannot attach a new session to a specific group automatically 

Proposed Solution

If I can click on a specific session from a specific group, and then when I try to add new session, it will automatically add that session to the group I'm working on and not to the ungrouped, it will be fantastic. Phenomenal. It will help me keep the organized method that I'm working with. And every time I open a new session, it will always go to the group that I'm working on at the moment. If I wanna, uh, have a new session added to, uh, the ungrouped area, I'll just click on one of one of the ungrouped sessions, and the system will recognize I'm looking for a a new session that can go there, and it's what added there. But as long as I'm working on a specific group, please add new sessions to the same group I'm working on. And you can identify that by looking at what is marked, which session. And if it's attached to a specific group.

Use Case Example

A good use case I have is me working at the moment on a group I created. And in order to kinda be efficient with the tokens and everything, every few minutes, uh, every few tasks, I open a new session. Now the session keeps opening up in the ungrouped area, and then I need to drag it to the group that I created so it will be organized. So that's a use case. When people are working on, uh, or working in an efficient way and they're trying to, um, attach sessions into a group, it's very easy to, um, to work like that. There there... they can also be a possibility where you just ask when opening a new session if I wanna attach it to a specific group, but I think it will be easier just to identify which group I'm in, um, by seeing which session is marked. And if the session that is marked is attached to a group, every time I do a new session, just add it to the same group.
