I have mix of Setting, Adventures and Mechanics with total of ~2100 topic/articles in my Dark Heresy 2 realm. Without Views, the navigation pane is just too big to manage during session. In addition, views provides super fast and easy way to filter just the necessary set of articles such as monster manual (full or partial), combat rules, items, psychic powers and etc. so many things you can do to make your life easier and so little views and slots
I spent some time playing with tags... watched all your great clips on YouTube and even though I see the benefit, the lack of convenient interface to do the tagging makes me a bit reluctant to proceed with 2000 articles. Bulk tagging is ok if you don’t have that much granularity but the need to pass first through a temporary view is killing me.
They first must implement multi-select option for the navigation pane and allow to make tag/assign/prune/scan/whatever operations on selection level. Otherwise is just too manual work.
