I’ve always used that kind of search bookmark, for many years, because I find it very convenient. It has long been my way of solving the problem with the previous site that using a generic search engine would return results for versions other than the one I’m looking for, a problem which at least now has a straightforward solution in the new site. When I post a link to a particular page in the manual here on the forum, I have invariably found it by searching for it using that search bookmark. You might want to try it rather than dismiss it out of hand!
The previous site was also powered by DITA, by the way, so let’s leave that aside: Lillie happened to mention that the documentation is written using DITA, but that’s always been true, and is immaterial.
For what it’s worth, in my personal opinion the new site doesn’t make it simple enough to browse directly to the manual for a particular version of a specific product, and I’ve of course passed this on to the manuals team. I also of course passed on my opinion that it would be preferable to hide the “sign in” link, since it offers no utility to end users (you might notice that the link is now labeled as “admin sign in”, which hopefully makes it somewhat clearer in purpose, though ideally I think it should be hidden altogether for us mere mortals who are not administrators of the site). You can rest assured that the team is well aware of the things that are imperfect about the new site.
The new site is built on a platform provided by a third party, and we have been working closely with them on the integration. Some of the things that we would ideally like to have will require additional work from the platform provider, so we will be subject to their own plans and resources as well. But you can rest assured that we will make further changes and improvements in response to feedback.
Incidentally, for me at least, if I visit the steinberg.help home page, on the right-hand side under Popular I see direct links to the front page of the Dorico Pro and Cubase Pro operation manuals:
You can save bookmarks to these pages as well.
I’m still considering exactly what we should do with the link to the manual from the Help menu in Dorico itself. With the former site, it could go to a single page that included links to all of the various manuals and ancillary documentation for the current version, but there’s currently no good equivalent for that page in the new site, which isn’t ideal. However, you should find that all of the new help buttons in dialogs and in the main window itself all still go to the appropriate place in the manual, allowing you to navigate on from there.
