1) Open the History, Bookmarks, or Reading List panel
2) Resize, rearrange, or change the sorting of any of the columns
3) Close the panel
4) Re-open the panel and notice that any changes to column sizing or sorting have reverted.
Changes you make to column size/arrangement/sorting should be remembered and not reset everytime that panel is opened.
Additionally, there should be the ability to double click a column header dividor and have it auto-resize to the size of the longest text it contains. This is a common feature of columns browsing elsewhere in macOS, e.g Finder and Music.
