hey @prusu01 thanks for reaching out. Your questions really are about a more deeper level than what we did on the toolkit. The toolkit is more of a wrap around for the helib library so it can be easily used. We don't support this much anymore but it's still available for download if someone wanted to work with it. We have moved on to the next step of our SDK called HElayers. https://ibm.github.io/helayers/. If you specifically are looking for HELib improvements, I would reach out the helib GitHub maintainers and see what they have plans for on their side.
