I added two - very smooth.
The roll-over question marks ARE very intuitive and helpful.
My only wish right now is that I could STAY in a certain My Plant List category and add multiple4 seeds, click-click-click. Then I would go to my Swap List and fill in details as I dig through my stash and count pkts and measure pinches.
(It would be eaisiest for me to just weigh representative pkts and then report the "quantity per packet" as so many milligrams. But I think that would only annoy people, and not convey useful information!)
