Hello!
We are interested too in the developments of the knowledge base tool. Adding some CSS would be good. At least in order to allow adding a tag-line below the search bar to give a better explanation of what the KB does (as it appears in HS knowledge base).
Another feature that would be good to develop is adding a tag stating the resource tipe (video, how-to, template to download…).
This being said, we are doing some tests to improve customization and noticed that the subdomain of HS Knowledge base is https://help.hubspot.com, while when I use the tool-bar and am redirected towards the articles, the URL becomes https://knowledge.hubspot.com.
The explanation I gave myself if that the actual domain on the knowledge base is https://knowledge.hubspot.com, but:
1) Knowledge base modules where cloned, moved into different folders into the design tool and customized there.
2) After this, it was possible to re-create a customized landing page using a different domain (https://help.hubspot.com). Under this page, it was possible to add the cloned modules and create a nice customized page.
I’ve tried recreating this procedure on our account and I was actually able to do it, even if it’s still quite complicated.
Maybe this can be a feature to develop?
