A Tags Repository is complete now thanks to medar. A few modifications later and here we go
You can now just like on Neocrome, browse all the tags by TPL, and see when they was added, along with seeing what tags are new in a version. You can even search for parts of a string for a tag, and even limit it to a specific file!.
The team also has a feature to edit the descriptions, and in multiple languages! So soon you should be getting details about them as well.
