Vanilla has some little bugs
Topic overview page and topics are clean and clearly arranged. Looks good!
But often I have to reload the page (browser reload button) to load all styles... seems to be a bug.
Lavender seems to work stable.
After clear browser cache and node app / nodebb upgrade most bugs away...
Still there and so should be a bug. Copyright overlays category blocks with Cerulean and Vanilla theme, but should be at the bottom of the page.
Both view of topic list and single topics is fine. Maybe I have to find out how to tweak / change the home page (categories overview).
