Love this theme. Great work @awesomerobot and @jordan.vidrine 
Not sure where to lodge bug reports & suggestions for Facebook-modern so am just dropping them here for now:
- Global pinned topics i.e. banners, push the left-hand navigation bar over to the right
- Banners are slightly illegible due to light blue background and dark blue hyperlinks
- Links for topic on the topic list appear to be links to most recent comment, not to OP. This is confusing for users as they often end up seeing nothing but the ‘footer’ after clicking a topic.
- Suggested topics are left-aligned, whereas the current topic is centred. I guess it would look better all centred?
- Be awesome if the onebox previews for topics generated from hyperlinks, were actually hyperlinked. i.e. if you click the image it will take you to the external site. Currently the image is not hyperlinked at all. Also be great if these opened in a new tab.
- Be great if the end of the excerpt read See more instead of
Read more...(also made bold to match FB) - Clicking the little speech bubble at the bottom of a topic, bring up a strange up/down spinner with timestamps that appears to take you the prev/next post (?). This is confusing. I assume this might be a bug?
- Onebox images are not displaying in the Topic list previews. Although they seemed to be intially, I’m wondering if this was only in the ‘leftover’ posts from when I was testing TLP?
I may make some PRs for this once I figure out my way around Discourse a bit more! Cheers
