What went wrong?
Please add this feature.

Did this work before? N/A

Please add this feature to pin tabs in chrome for android. I open a lot of tabs and also use the close all tabs option but there are some tabs that I want to keep when I use close all tabs option. So pin tab is very important and necessary feature for me.
