I just have some small cosmetic suggestions, some of which would hopefully improve usability by a small amount as well:
a)
https://www.lfs.net/forum, Last post column - bold up the topic name along with it being blue and clicking on it would always take you to first unread post. Go to last post arrow feels quite useless and contra-productive. Maybe you could change the arrow to go to last unread post instead.
b)
https://www.lfs.net/forum/subforum, Last post column - arrow action is like I wish it to work from the main forum. The post authors are harder to distinguish than in the main forum column because the share same color/font with the other info.
c) Give us red tanned devs back! Mods too! Is this the first time Scawen uses avatar here? Man, he camouflaged too good now.
d) For the love of God please do something about the notepad-ish looking forum posts! Give them some bluish hue or something. Please!
Oh yes one more thing, all my outgoing PMs are wiped and all incoming ones are put into root folder. All previously created and categorized folders for the incoming ones - also wiped :sadpanda:
