Add the Ability to Remove Some Toolbar Buttons

[lumberbot-app]

Apologies if this is the wrong place to post this.

It would be nice to be able to remove some buttons from the toolbar. After adding some extensions my toolbar is overcrowded and spans two rows, but some of the buttons I never ever use. In particular the 'CellToolbar' button, presentation buttons, and 'Code/Markdown/etc' button use a lot of real estate for no useful functionality for me personally. It would be great to have a little config menu to deselect active buttons.

@takluyver commented: Hi Mike - issues relating to the notebook user interface are best on the notebook repo. This repo contains a Python API for talking the Jupyter protocol.

Let's see if this works:

@meeseeksdev, migrate to jupyter/notebook

@Carreau commented: nah, it's not enabled there. You need to go to https://github.com/integration/meeseeksdev and enable it. I've done it. I'll restart it and retry.

I'd like to +1 this, or a slightly different variant:
even though we have the option to disable extensions one by one, having one keyboard shortcut - or an api - to hide/show the whole toolbar would be a plus.

PS.
I take it meeseeksdev is some experimental triage-assistant thingy; for what it's worth, I just wanted to outline that on this issue we've lost the identity of the initial requestor; it's accessible of course through the link but that makes it two clicks further - counting the one to come back here. just saying..

Unfortunately Github doesn't make it possible to migrate an issue and preserve the identity of people making the comments, but meeseeksdev does record who opened the original issue:

Closing as fixed in Notebook 7:

This can be done by opening the Settings Editor and clicking on "Whether the item is ignored or not":

Then on the notebook page:

This can be done by opening the Settings Editor and clicking on "Whether the item is ignored or not":

I don't get to see a third Settings tab after Files and Running, how does one go about enabling that ?

[jtpio]

It will be added after clicking on Settings > Settings Editor

thanks !

so I have been able to use the UI in order to remove the last 2 items:

• Open in... aka interfaceSwitcher
• The kernel name aka kernelName

and have observed the change to be stored in file
~/.jupyter/lab/user-settings/@jupyterlab/notebook-extension/panel.jupyterlab-settings
where the toolbar key now contains

        {
            "name": "interfaceSwitcher",
            "command": "",
            "disabled": false,
            "rank": 990
        },
        {
            "name": "kernelName",
            "command": "",
            "disabled": false,
            "rank": 1000
        },
       <snip>

now, in the perspective of deploying ready-to-use containers for students, what would be in your experience the best way to have this as a default ? I can pre-populate this file of course, but are there other more programmatic ways to achieve the same result ?

to give some background, we used to achieve this kind of UI customization in the context of classic using custom.js and custom.css; are these still active hooks with nb7 ? I understand I could write an jlab extension for this sort of things, but it feels a little overkill; or is it ?

sorry for the flood of questions ;-) and thank you for all the work and the valuable insights !
