Suggestion: To have the ability for each folder’s window to have its own column settings.
Right now, I am archiving some email around a specific topic and putting it in one particular folder. Because these are email messages, I like to have my column some “From”, “To”, etc. However, when I make these column setting changes, the columns of my other folders (most of which are not email related) change. There is no point in have a folder full of rich text documents and PDFs to show the “From” and “To” columns.
Hopefully this will be addressed in a future minor revision update.
