I see that using File-Import-File I can import a .CSV file as a Sheet.
This is a really helpful DT3 feature. However I see two tweaks that would make it much more useful:
(1) Even if I designate a given column as a URL, valid URL addresses in that column are not active as hyperlinks
(2) There does not seem to be any way to wrap text on long text fields (This was discussed previously in a slightly different context - i think Development may be working on this)
