Working with multiple cells without a notebook

[sok82]

Problem

I'm working on an app that must enable user to add, change and remove cells and certainly give him a chance to write and execute code in these cells. But I don't need full-scale notebook with all it's functions.
Is this possible with datalayer components?

Can you please provide some example of how can I work with multiple cells

1. Add cell
2. Remove cell
3. Execute code in selected cell
4. Execute code from a number of cells
5. Reacting on cell events (input, selection, code execution etc.)
6. Styling cells (I suppose CSS rules would be enough)

The only thing that I had found in examples is the example with one single Cell component here

But it's unclear how to work with multiple cells.
For example when I add more than one cell I have following issues with an example

1. Run action in toolbar doesn't seem to work
2. Shit+Tab action also doesn't work with the second and following cells

Suggested Improvement

1. Include an example on how to interact with multiple cells
2. Include some description of props \ events for components
