@stephanekassis just want to clarify some things. Are you just looking for stylistic changes?
Are you looking for the chat window to be "docked" to the bottom of the screen?
What kind of changes are you looking for?
@pichalite I'm using the latest NodeBB v0.9.3.
I have managed to find a fix by another user: https://github.com/neutrino84/nodebb-plugin-category-sections/commit/ce3ba115a3e6f49912f9a79be415409c73b377a2
This seems to work without issue.
