For 2, why not just create a wordlist called "Ignored" and use it that way.

For 1, removing words from loaded wordlists to move them someplace else can not be done when the Spellcheck Dialog itself is open and being used. Closing it and then editing the wordlists is required.

This happens as these lists of words are loaded into a hash table that can only be added to efficiently. To delete entries, you must destroy the table and rebuild it from the edited wordlist.
