Our browsers now ship with a nice startpage by default. Its created using a great project named Homer.
We now have our own Privatebin instance where you can post longer logcats or terminal output.
Also feel free to use the selfhosted Cryptpad instance found here for polls or similar stuff.
This is amazingly cool. Big 
from me.
Is it worth putting the pastebin into the top menu links (e.g. "Paste)?
Do you mean the forum topmenu? 
Yes; if that makes it too long then maybe have “About us” “Downloads” “Gitlab” “Paste” ?
I didn’t, I don’t tend to use dark themes (I’ve set even Discourse to the boring light theme… 
).
(How about a light Garuda theme? 
)
You are an admin now you can also do it
As in more than just Firefox? As for the rest in your post really sounds good.
EDIT:
OK got it and it does look good with the wider buttons and the dark theme. Very nice job.
I don't see that same screen. 
Turn on dark mode? 
I didn't have all the choices that are on that screen shot. After a reboot which I did earlier which didn't make a difference is now showing all selections.
Firefox browser?
To long sentance, in short, it work now for you 
Have you looked at this, looks a lot nicer than homer
My question is, why do you need to deploy what’s essentially a static HTML webpage using Docker?
