I have filtered on a column and want to create a new item. Hitting enter does not create a visible item (yes, I know the item has been created, but since it does not meet the filter's criteria, it is not displayed. I can however create a new item by right clicking or using the menu. The same applies to sub items.

 

Now here is the bigger inconsistency. If I use the menu to create an item or sub item, I can create further siblings by hitting enter.
