afc2add (TaiG AFC2) now shows up on the installed list and therefore is easier to remove if you don't want full access to the file system via USB to be enabled. It's a security risk since it isn't password-protected so some people prefer to uninstall it and use OpenSSH instead (after changing the default root password).
Aside from that, they don't typically add features to new jailbreaks. It's really just a matter of making them available to us. The features and bug fixes are in the iOS updates. We just need the jailbreaks to be updated to work with them, or new jailbreaks altogher if the exploits are closed, so we can install the iOS updates and keep up to date.
I noticed yesterday that Shrink was updated for IOS8. I downloaded it but after, I realized that Springtomize does everything that shrink can do. One thing I did was change the color of my text under my icons with Shrink. It was after I did this that I noticed a customize text setting in Springtomize. I tried changing it there but Shrink superseded the Springtomize setting. Now if only Springtomize had the scrolling dock like Infinidock, it would be "almost" the only tweak I need on my phone.
