Me and my team just recently moved from Trello to Asana but we are having a hard time with documents. We need PREVIEWS trello like, for PDF, DOCX, and PPTS. In Asana we need to download to view, it would be awesome if that file could be previewed in browser, we preview a lot everyday. we have remote workers and its better to not have lots of versions downloaded.
Also It would be nice to select a lot of cards and deleted them, or delete columns that contain cards, we moved using migraorxyz and now we have lots of duplicates.
