Yes, I like the "View only: Have or Want" but it needs to be differentiated from a 'Have" like what I have in my inventory as opposed to "Have" what I available for trade.
Now as far as the alphabetical listing, using my categories for example, my daylilies are listed backwards by cultivar name starting with the W's. Looks like it may be that way based on what I entered last?

Same thing with Roses and Iris.
My Perennials and Succulents are done according to genus as you said but the cultivars are listed backwards as well.
