It would be great to have a tutorial on how to use Mike Bostock Collapsible Tree http://bl.ocks.org/mbostock/4339083

Most Python IDEs have some sort of pop-up help. e.g. hover over a function (built-in, library, user defined) and get a pop-up showing the signature.

Also highlight (e.g. with red squiggles) errors in syntax. Highlight in blue squiggles using a variable before definition, etc.

I was able to open the first 5 tutorial notebooks without a problem by clicking import on the welcome page. However, for the 6th tutorial I cannot open it using the same step.

I put in this command !ls to list all the files and I see it there. However, i cannot access it from the sidebar.

Managing notebooks is not easy when there are many notebooks, even though when I create tag panel and arrange them into tag panels. For example, I need to delete some of them together, or tag them, etc. I need to see all of my notebooks as a tree in a bigger page.

There is no confirmation to delete notebooks/data, or the ability to recover delete notebooks/data. This is dangerous! :O

I ran into this small usability issue. When I logged in with my user (cangiano) the OAuth2 server asked me to approve special permissions, only to fail to show me the list of required permissions. Clicking "Allow" lets you through, but it might be confusing for some users. Furthermore the "Save Consent" option doesn't appear to actually save the consent at the next login.

See https://www.evernote.com/l/AAG97TbetTNMSImxEpixDDCN5X0QvxhySbI for reference.

This is a small usability issue. After clicking on the link within the confirmation email, and setting a password for the first time, the user is finally registered. The page however will redirect him or her to /register after having just completed their registration. The desired outcome would be a redirect to the homepage (if the user session is kept) or to the login page (if it's not).

When I have many notebooks and some of them are running, the kernel does not get started. So, I have to go through all of my notebooks, find the ones that are running and stop them. I need a feature to show me all of the running notebooks in one screen, instead of checking each of them one by one.

Happens in Python (not sure about R), but sometimes when I am running a cell, as it is processing, the notebook in the sidebar "jumps" from "Recent Notebooks" to "Recent Data". The kernel remains active.

I will try to post a sample script that is reproducible, but right now this issue appears very inconsistently.

In Python notebooks, you can use tab to autocomplete a command. Would like the same feature in R.

When installing a package, can we please suppress the output:

Installing package into ‘/home/notebook/R/library’
(as ‘lib’ is unspecified)

It is a bit strange to see the side bar on the right. Common convention is to have it on the left of the notebook.

Every time I assign something using "<-" as in:
a <- 1
the next line becomes auto-tabbed, because it thinks that my line is incomplete.

Please make the notebooks recognize the "<-" as variable assignment.

The coloring difference between Markdown and Code cells is a little too subtle. Would be great to be able to change themes (e.g.: dark theme for Code, light theme for Markdown).

In the sidebar, if I click on "See all notebooks" or "See all data", it opens a new tab called "Search - type notebook".

Once this is opened, there is no way to close it.
