Steps to reproduce the problem:
1. Open many tabs (like most users do)
2. Discover that you need to refer to two tabs at the same time
3. Try to press "Ctrl" + "Tab" to switch to the previous tab to look something up

What is the expected behavior?
Focus should switch to the tab that was used most recently. If I keep holding "Ctrl", then there should be a list showing up of the N most recently visited tabs. Pressing "tab" again should switch to the second-most recently used tab, and so on.

What went wrong?
Tabs are navigated in the order that they appear on the top. Ctrl + Shift + Tab lets you navigate the other way.

Currently, to accomplish the above, it is necessary to:
1) Move the two tabs of interest next to each other
2) Use "ctrl" + "tab" to switch to one tab, and use "Ctrl" + "Shift" + "Tab" to switch to the other. The user has to remember which tab was in which location, because pressing "Ctrl" + "tab" twice in a row would put the focus to a totally different window.

The fix would be to provide a setting to use the "natural" behaviour of the "Ctrl" + "Tab" shortcut that the users are used to from interacting with most other programs where multiple windows are open. Turning this setting on would allow the user to keep the same workflow as he or she is used to. Examples of such programs: Visual Studio Code, Android Studio, text editors, etc.
The lack of this setting is a pain point in having multiple tabs open.

Did this work before? No

There are some 3rd party apps that let you accomplish this by various hackery, but the proper solution would be to simply build this feature into the Chrome. Even if only a single most recently used tab were to be supported, it would already be a tremendous win.
