1) There seems to be lots of links in the Talmud that aren't actually linked. E g all I get when I click on the links below is a little popup telling me what the abbreviation means -- and even that I have to click to see, and click to get rid of; it doesn't show on hover.
2) The TOC of the Jerusalem Talmud is organized by division. The TOC of the Babylonian Talmud is organized by volume. That means an awful lot of folder opening for a novice like me who doesn't know in what end to start looking for a particular tractate. And when you've finally got it all opened, it still makes it harder to find the right one, and it takes up more space, requiring more scrolling. (Plus the last major update destroyed every one of my opened TOCs and set them back to default. 
)
I realize you're probably restricted by the printed books, but if the Babylonian TOC could be made to look like the Jerusalem one, it would be much more helpful. The volume number doesn't really mean much in an electronic version. And I bet the hardbacks have the tractate[s ] on the back. Imagine if you had to drag each volume out of the shelf before you could see what it's about.
