I appreciate that some users prefer to sort keywords as required. But for those of us that would find it immensely useful to have the option for keywords to be sorted automatically, I wish!
Sorting as required involves a lot of time: one has to be very disciplined to ensure for example, stra precedes stre. With dozens perhaps hundreds of keywords, sort automatically (ascending or descending) would save a huge amount of time. Personally i find it easier to find a keyword from a sorted listed (a,b,c, and so on) than have to manually drag and drop keywords into order.
