While it would be rather token-intensive, I would appreciate the option to (for a specific query) be able to toggle whole-tag context: i.e. for the entirety of previous threads to be reviewed for context. This would be a kind of Notes (planned) feature on steroids, but also be selective where I can choose when to tap into additional context or not — rather than having universal context that can't be opted out of.
I can envision the option for this residing in the drop-down menu, along with an (i) hover info button that warns the user about the increased processing time and token burn that would occur if activated.
Some obvious qualifications: this would not work with all models, given differing context windows, and the user should be informed of this. It would also require threads to be pre-tagged with some length/token metadata that would allow for the potential of their use to be easy calculated.
