Forum feedback

I was thinking of giving some feed back, on forum. The style is neat but those scrolling barsare too much. It feels like its trapping the eye.
May be eliminating the empty grey space on the sides would be space eficcient. Alternative would be splitting the similar topic to the right and created topic on the left, shortening the topics list. For PC.

For mobile or vr, this can be a 3 panels that are swithced within the device, alike desktop pages.

May be useful.
