Steps to reproduce the problem:
The situation: Being a hardware test engineer, working with hardware validation engineers, contract manufacturers and vendors, I often have many chrome browser tabs (consisting of Google docs/sheets of schedules, meeting notes, test plans, test result data, and test setup instructions) that I need to keep track of and leave open, but I become unable to get a quick idea on what is in a tab until I click on each of them to see what they are.  

Feature request 1: Request to add a feature for a  "table of content" showing all the tabs that are open, including titles of the tabs and a few first lines, and maybe a thumbnail of what is inside the tab, so the user can glance at it and know what all tabs are about. Selecting the tab in the table of contents should move the window to that tab.

Feature request 2: Request to add another feature that when the cursor hovers over the tabs it shows a quick preview animation of the tab’s content, without having to click on each tab.

What is the expected behavior?
The expected behavior is that since there is not a table of content or content preview to help enhance the user experience and increase productivity, when faced with too many tabs left open, the lack of this feature makes it difficult to identify which tabs are which.

What went wrong?
The lack of a table of content, or content preview, like such found in an open pdf file with a sidebar preview, makes working solely on chrome browser tab less productive than I'd like.
