I honestly think getting rid of it would be fine... the latest post in each forum is already shown to the right of each forum anyway, for people who for whatever reason are wondering what's been posted last in each forum or whatever.
I agree that where it is now is pretty bad...especially on phones, I'm like "what the heck is all this random crap I'm scrolling through?!", hahah.
Overall, I like the new theme, though. The only other change I'd try is messing with the two gray colors at the very top of the forum, where the profile buttons and stuff are. Having the dark gray be the "overlaid" part feels weird. I understand that "dark gray = clickable space" matches the logic of the rest of the theme, but the top GAME MAKER part looks so weird in light gray to me. My two suggestions would be either:
Just use the background dark gray for the top. Or:
...Give the top its own shade of dark gray, just slightly lighter than the background gray to make it look like a separate element.^
Please take them into consideration. That light gray is weirding me out every time I see it, heheh. The rest of the theme looks so pretty to me, too!
Edit: WHOA FAST. X'D
Thanks for trying them out!
Edit edit: Yes, this is gorgeous. Lightening the bottom portion was a great idea. Makes the bottom look more cohesive now, too! Thanks, Nocturne. Now my twelve hour programming days interrupted by looking at the GMC every ten minutes will be 20% more pleasant, hahah. =D
