Whether it is a terrible design, or non-functional is in the eye of the beholder. Many of us are using it just fine. V10 is different from Legacy and it will take time getting used to it. If you are expecting it to behave the same, you will be disappointed. I've gotten used to it and prefer it over legacy. For me, v10 is more functional. Obsidian is on my watch list for a plan B if I ever need it. It is very flexible and has a lot going for it. It is the Mr. Potato Head of note apps. Using plug-ins you can fine-tune this to be whatever your specific use case needs. That is a big attraction. Currently, v10 is doing what I need, and I prefer not to spend the time to create and manage a note-taking system, but I completely understand those that do.
