On nowcado.com it is now possible to edit the name and image shown for an item, and to see the history of every previous name and image (similar to wiki sites).
On an item’s detail page, when you hover over the item’s name at the top of the screen, a pencil will appear:
Clicking that pencil gives you a dialog which lets you upload a new picture (click the “Choose File” button) or switch to a previously uploaded picture from its history (using the dropdown on the left):
The history is presented in the dropdown from most recent to oldest.
These features should make editing data on Nowcado much easier. Let us know what other data editing tools you would like to see!
