I have played around with the new custom list creation section a bit. Overall, it is a nice overhaul. It is much more intuitive.
A couple of small notes:
1) I noticed a glitch where I would enter a definition and then Skritter would still show the word on the list as still requiring a definition. When I saved that section of the list as a whole, it showed the definition I added.
2) Numbering the words for list making purposes might be useful. That way we could do a quick check to see if we are getting near the total number of items a list section is allowed. The first item we enter would have a 1 beside it. The second item a 2. It is also useful for cross referencing lists at times.
3)Sometimes, when I am adding a new section to the list, I get put right into a prompt to start adding words. Sometimes I don't.
4) (Serious Bug) This just happened. I am making this post as I make the list so I don't miss anything. My list as a whole just locked up. It is a list of words from a notebook I have from my time in China. Each section is labeled page 1, 2, etc. I can still access page 1, but several of them just show me a blank white page. The page labeled no name was originally page 4. If you click on it, it comes up, but instead of saying no name, it says page 4. That link does load, though. I had all of these words saved on an excel spreadsheet, so I am not out much time, but until you investigate that bug, that list is locked up.
