Describe the feature

Similar to what exists in Spyder, it would be nice to have access to the IPython console when running python code interactively using REPL to allow running a file and running additional commands. There could be a setting to automatically open or not the console whenever a line or cell of python code is ran interactively.

Environment

Zed: v0.165.4 (Zed)
OS: Linux Wayland fedora 41
Memory: 15.3 GiB
Architecture: x86_64
GPU: Intel(R) Graphics (ADL GT2) || Intel open-source Mesa driver || Mesa 24.2.8

If applicable, add mockups / screenshots to help present your vision of the feature

Here is what the console looks like in Spyder :

I also believe it would be of great use. I often work in python and the ability to executes cells from a file is great but I often want to run one liners or arbitrary code that i do not want in my file. It's also nice to not have the cell outputs to be inside the editor area.

For what it's worth, it's currently kind of possible, by locating the kernel file with the magic %connect_info and then opening a jupyter qtconsole connected to the kernel with: jupyter qtconsole --existing /run/<...>/jupyter/kernel-zed-<num>.json.
I did not find a way to open an ipython console connected to a kernel (rather than a qtconsole, which is a standalone gui app).

Of course it should also work with other REPL too, that probably have different ways of connecting to existing kernels.

Seconded! VSCode's "Interactive Window" is a similar feature I love and currently miss in Zed. It runs an ipykernel and integrates seamlessly into the IDE, supporting features like plot display. It also detects cell markers in .py files ("# %%" or "#%%") automatically, allowing you to run an entire cell (lines between two markers) with a keyboard shortcut.
