Sounds like you'll more likely than not be crafting that terminal yourself; I'm unaware of any that goes the lengths you seem to desire. But that's actually not that big a deal nowadays given the quality of LLM agents.
there are a few projects with interesting ideas already, warp terminal, which was recently released as FOSS is one, ttyphoon is another. both are not yet where i would want them to be in terms of data display, but they show that reinventing the terminal is possible and hopefully these ideas will get more mindshare
I honestly don't get the deal with Warp. Ttyphoon does look interesting, but it's at least 3 years old and still alpha; doesn't inspire much confidence to be used as anything more than a toy. But then again I've been using Horizon[0] since its debut here, despite encountering some alpha edges. Made a few changes, and now working on a port of it to Python.
But again generally I really don't see these projects going the "full" distance as the processing to presentation pipeline is already generally solved.
ttyphoon is mostly the work of a single person, who is also working on the murex shell. some projects take longer to gain traction. i am mainly interested in the ideas being explored, and hope that more projects pick them up. i haven't yet had a chance to try it myself.
i also didn't try warp yet. it just came out as FOSS and i am waiting for them to implement the option to disable the AI functions which they promised. what i like about warp is that it treats the output of each command as a separate entity that i can work with. a lot of power comes from that. also the separation of commandline and output if i saw that right. wave is another terminal that does that.
i'd like to take that idea even further. having separate output boxes means that each box can be used differently. i could for example run an interactive program in a box, such as an editor, or a filemanager. even a graphical one. heck, even a browser view. so basically, can treat each box as its own window without the clutter of tabs or windows that i would get otherwise. the potential of this interface is massive.
