@fcollonval Can you please tell me what exactly I need to do to use this to get a non-blinking cursor.

[fcollonval]

@gloryVine first of all this is only available in master (or in the freshly released v3.1.0 beta 0). You can install it with:

pip install -U --pre jupyterlab

Then you unfortunately need to set the 4 configuration parameters.

1. Open the Advanced Settings
2. In Notebook duplicate the settings for the three cell types and change the cursorBlinkRate (0 to stop blinking and negative value to remove the cursor):

3. You need to do that in the Text Editor section too

@fcollonval Great, this works. Thank you so much.
