Wrong DataFrame reference

I was recently working on a project and was executing some cells with dataframe from my custom dataset but suddenly I got the wrong column name key error and after printing the df I found that it's not my custom data but the df made of the iris dataset which wasn't loaded anywhere in the project.

Follow collaborator while editing

Hi, is there any feature to follow a collaborator while he/she is editing or moving between cells? It seems hard to click on Collaborator's name at the top bar to find the cell being edited. I am looking for something like the follow feature in the Live Share extension of VSCode.
