Lockable inventory and mass sell button

[qoph]

Many people farm maps and most of the time, you want to mass sell everything but a few select items in your inventory. It would be very convenient to be able to "lock" certain items in your inventory and have a mass sell button that you can click that would sell everything but the locked items. You can already recover accidentally sold items, but if you wanted another failsafe, you could put in an automatic popup dialog box that warns you if you try to sell anything epic or above (including vanity).
