Delete a wpt folder or a group of wpt ?

[Werner]

it's not difficult import folders with waypoints, airports etc. , but to delete, must we cancel any one separately ?
Can we also cut, copy or paste ?

Unfortunately it is impossible to delete group of nav items., but you can delete folder (which contains a lot of nav items and folder). I will improve this in the future...

Copying - long tap at item which you want to copy and in context menu select Copy
Pasting - long tap at list where you want to item and in context menu select Paste
