saves horizontal space while in bins, by hiding columns that aren't needed
Saves horizontal space in the bins, by automatically hiding the columns that usually aren't needed, and by changing the column header "Taggings" to a simple "#".
The Canonical, Synonym, and Character columns are hidden automatically in the bins where they're usually not needed. For example, the "Canonical" column is always "Yes" while you're viewing the canonicals bin, and always an unticked checkbox in the synonyms bin.
To get the columns back, you can click the button in the top right corner of the "Tag Name" column.
