The newly-released 1.08 adds the removal option you requested, but only in the premium version (I don't plan on adding anything else to the free version except fixing any bugs that are present in it). I'm unable to replicate your error; is this happening with my plugin as the only one enabled?

Well, now it seems to be working. Not sure what the null was that tripped it before. But I'll grab the full version now!
Only other question I have is if there is a way to extend the section for the item name or allow it to drop down a layer? The item name, plus the price, plus the quantity ends up overlapping itself.
