Bookmark names ellipses on Chrome
As far as I know, there is no way of getting rid of those ellipsis and make more space available for the bookmark names. Some past tricks existed for making the font smaller, so fitting more characters in the allocated space, but these were not very useful.
The only method I can suggest is to create folders in your bookmarks bar and store the bookmarks in them. The contents of the folder will appear in a drop down list once it is clicked, and the names will appear in full:
You could have a mixture by leaving bookmarks with short names in the bar and only put the ones with long names in the folder(s).
This idea is not perfect, but I don't know of a perfect solution to this problem.
