pre-selecting a table row
I'm wondering if there's a way to pre-select a table row, similarly to that of a dropdown or multiselect component?

differences between mo.ui.dictionary and python dict?
I find it unclear from the documentation, why I should use a marimo dictionary, and not just a python dict to hold UI elements. What is the fundamental difference, and when should you use one, and not the other, and vice verse?

running async inside sync cells
I have a long chained function call, which needs to call some async function to fetch data from a database. I was thinking I could use asyncio to get the running loop, and then run the function inside that loop using "run_until_complete", but I just get an runtimeerror "this event loop is already running". How can I handle this without having to rewrite all my functions to async instead?

Interactive plots with Plotly
I'm looking for a way to generate a plot based on a plotly canvas. I want to create a surface, by clicking on the canvas so that vertices of that surface can be defined. Later, I want to extract the vertices, to be able to fine tune them in my UI. Is that something I could do with Marimo?

Creating a UI component that can update itself
I want to create a batch element, where a drop-down lets the user configure the content of the batch elements, such as having additional features revealed if choosing to do so by the user. For that to work, I need to re-run the cell that generates the batch element. Is there a method to re-run the same cell? I was thinking I could use states to trigger this, but if states are set from the same cell, they dont trigger an update. I couldn't find any documentation about this type of reactivity, as it seems cells can only trigger other cells and not themselves.

Possibility of modifying object to which on_change handler is bound
I'm looking for a way to modify an object if it's value changes. Specifically I want to change the label of an object, if the value changes. I can add an on_change handler to detect changes, but once the object is created, I can no longer access it's internals. I tried asking the #ask-docs-ai channel, but I think it's hallucinating: https://discord.com/channels/1059888774789730424/1228123354607648788/1255236745717485568.
If the "self" object was part of on_change function, i.e the function signature always contained "self", and if "self" objects, for which the on_change functions are bindable, could have their property setters, i.e. label, value etc. exposed, then I think it should be possible.
