Bookmarks Tab Pinned

A bookmark manager is displayed on the leftmost in the state of tab fixation at a Chrome start-up.

Nothing is done when there is already a book Mac manager of a tab fixed state.

I think that it is a delightful function to the following directions.

-Since it is hard to use the pulldown display of a bookmark bar, you always want to display a bookmark manager.

-Since a fixed tab is certainly generated at a start-up, the mistake which clicks x of the last tab carelessly and it terminates can be prevented.
