just to say : i replied to you directly anyway, but just so others can read the answer to that one here it is too.

re 1) are we talking about a note send by the customer to you (i.e added to the order) , or a (fixed) note you set ?

re 2 and 3)
all that’s in there at the moment is the order history (with a print button next to it).
I’d say just download and install the plugin and have a look what’s there

i will – in the not too distant future – do something a bit more detailed regarding reporting, but – to make this more usable – i need to change a few things in the plugin/code , so there’s no ETA on that one yet as such I’m afraid

re 4)
this kind of goes hand in hand with what I said about the reports. so, not as yet. sorry.
