My first kneejerk reaction is that the navbar on the left takes up too much screen real estate (I'm viewing on a laptop). I might feel differently after getting used to the new design but that's my first and strongest impression.
-- I am taking all the feedback posted here into a list of things to consider amongst the admin team. Please continue to leave candid constructive feedback, and I will answer the questions I can. I've set aside a few hours for this.
I'd really really like to have links to gaming, off-topic and politics in the top bar. As it stands, it is mostly empty anyway. I'm not a big fan of the sidebar because I read from left to right and it gets in my way. I know you can blend it out, but switching it on and off is a bit of a hassle.
The "dark theme" needs a bit of work. Dark grey icons and text (new message & text editor for example) on a dark background isn't so great. Also, the orange line around the text editor is kinda weird.
The "likes" should be displayed on the right side, right above the like-button.
The white background for the emoticons is also quite jarring.
"Insert link" and "Insert image" also have white backgrounds, contrary to the other edit buttons.
As for the rest, I like it so far. Good readability and clean design. Keep up the good work
Another thing I would say about the hamburger button ... it adds at least one extra click when swapping between sub-forums. I used to just have to mouse up to the top and click the sub-forum I wanted to go to. Now I have to mouse up to the top, click hamburger, then click the sub-forum I want, then click the hamburger again to get rid of it.
This might not seem significant to some but for people who click around a lot (like me) I can see it taking away from the user experience.
@strange headache Agreed on quick links for main forum areas on top nav, that's a priority to-do list item. Will let desktop users keep the sidebar closed if they choose and navigate GAF the classic section-jump way that I've been accustomed to for a couple decades, yeah.
Other issues you've noted we'll go over in detail in the coming days, thanks for the detailed feedback.
Suggestion - on mobile to see my alerts I have to open up the hamburger menu to see if I have alerts. Can that just be moved to the top of the main bar...main site heading I guess it would be called? Alerts should be visible without having to go look for them.
