Newest browsers, MultiDrag: Touchscreen, you can drag many cards at once with each finger.
+ Use case: Many users can drag their own card at big touch screen. Or one user can drag many cards.
+ There is not any kanban software with MultiDrag feature yet.
+
+
Ladybird, OneDrag: Touchscreen, drag only one card at once. Is it possible to get MultiDrag?
+
Legacy Browsers: Uses HTML4 tables, and GIF image for rounded corners, to be visible at Netsurf and Amiga IBrowse.
+ No drag drop features, so there will be buttons to move cards.
