Improvement: Add new item on pressing enter

[soderluk]

Pressing enter when adding new checkbox items should insert the new item and allow to immediately insert a new one. Currently you have to press the Add new item button. This is quite counterintuitive and is slow, if I want to add many items in a row.

Hey again!
This feature is planned for the Usability update. I too am very annoyed by the lack of this feature.
