Hey, nice extension. Just tried it, and it works great!
Below are a few things I observed:
I didn't set a category in Blog settings. I thought it was optional.
Later it kept asking me to choose a category. I went ahead to select one in the settings, but that didn't reflect in my blog editor. It required the page to reload.
I did and lost all my progress.
To combat that, I installed FoF Draft so that I don't lose my blog progress next time.
Turn out it isn't compatible with this extension and broke the structure of the site.
So basically, if you forget to choose the category in extension settings, then this problem will arise again.
You should add that to the UI and make it mandatory for the users to select at least 1 category for the blog.
Also, is there any way to control or edit the permalink slugs generated by the extension?
