At the setting of manage containers, after renaming the name and changing the color and icon, there is no Confirm(OK) Button.
How to confirm the change？

I have re-arranged the order of the containers. I can see the arrangement of the containers is updated successfully when I click the extension button to preview.

But if I the right-click the tabs, the order of the containers is still remaining the old sequence which has not been updated.

There are only 8 colors. So, I hope there are 50 types of different color.

Because most icons are not my favorite. I can only choose the circle to use. So, I hope there are 50 types of icons for users to choose.
