New version of Biostar has got tag auto-completion working. It took about 9 months for this feature to be re-implemented into the site since it was taken out of SE 1.0. software, which can be considered a looong time in Internet scale of time. This could make the site workable for me again. One of the other most important features, which is the suggested existing Q&As once the title has been typed in, is still not working (or not for me). I hope it won't take another 9 months to have this feature on again.
