Move several tasks/memos from one task list to another
In the Task and Memo list view: The only way to move several tasks from one task list to another is to select the tasks, then Edit->Copy, then select the destination task list on the left and then Edit->Paste.
It would be great if it could be more intuitive. One suggestion: Add an entry "copy/move the selection to the task/memo list" to the context menu and possibly menu "Edit" (or "Actions").
