Actually, lp user X meta clear will clear everything, including options (lp user X meta set). I'd like to have a command like it, but only for prefixes, like /lp user X meta clearprefix or so, then I can remove ALL prefixes with ALL priorities from the player.

• /lp user X meta clear prefixes
• /lp user X meta clear suffixes
• /lp user X meta clear chat (both prefixes and suffixes)
• /lp user X meta clear meta (just meta (option) key-value pairs)
