Quad view like JSFiddle (2x2 grid) or other ways of seeing 2 or more of sch/ brd/ 3D side by side.

I'm very much a multi monitor user and when working in KiCad will almost constantly have the schematic on one monitor and the PCB layout on the other monitor, or the PCB layout on one monitor and the 3D Viewer on the other, depending on which thing I'm working on at that moment. Point being, while it's not horrible switching between the tabs of SCH/ PCB/ 3D in the current website, the quad box view that JSFiddle has could be a cool way to see all the changes happen live side by side, and perhaps later some deeper topics about being able to break out each of SCH/ PCB/ 3D into separate windows or some such.

We used to have this! It did add some complexity but it's a good idea to add it back in eventually. Currently the circuit is "rendered" (which in the case of tscircuit, somewhat confusingly means it is "compiled") in the browser, so having two windows open works, but it will cause a lot of extra computation.

I think the "split view" is a good idea, we used to have this but i found personally that i didn't use it much because i was usually designing the schematic and doing the PCB design in separate stages. But with AI circuit gen, it is useful to have both i think
