Theres no way to tell whether a cell output has been collapsed or not, or if cell execution is just not working.
I.e. if you collapse output of a cell, there's no indicator to tell whether cell output has been collapsed.
Feels wrong, I spent a few minutes trying to debug this simple thing.




Jupyter displays a little handle that one can click on the expand the output, i.e. a visual cue that something is there..

Do we support collapsing?
Collapsing cell output with o key.
A visual indicator for this would be great! Separate from this, it would be great to have a button to collapse the output, similar to how you can in the normal jupyter interface
Probably, it would be good if you would be able to click the visual indicator for collapsing/uncollapsing. Because a way to collapse using the mouse is missing as well (cf. @EntilZha)
