I agree with everyone about the color scheme, looks great
My main suggestions:
-I’d rather have the page navigation buttons on the main viewing area instead of having to press “#.” Perhaps you can have next page and previous page buttons displayed by default and the full page navigation menu under the “#”
-I’d love it if the mobile posting screen was more like the PC version (as in having the smiley menu, the area showing recent posts for reference, and the tags menu). Perhaps these can be in pop-ups like you currently have the page navigation.
-If you could show mini-profile pictures next to posters that’d be great, but I’ve noticed you’ve indicated you don’t care much about the profile pics
Finally, a minor bug I found: I switched to the mobile mode using the board preferences, but the “switch to mobile mode” link still appeared at the bottom of the screen.
Hopefully these comments are useful, overall I do really like mobile mode
