Is this the chat on the side or the agents feature?

I have to admit I'm not clear the difference? It starts with the list of your sessions/agents . Then starting a new "agent" or question or plan. I usually use each agent for a few questions or prompts at most. Occasionally it runs longer than that.

I love using it for the chat question style where I ask it things like:

For these frontend pages with X options collect the database tables for each.

This is of course something easy to do manually, but I like it stepping through a couple functions much faster than me searching around manually and maybe getting lazy and not checking all of them.

Both are great, and analogous to Cursor which has both features too.
