Forums in columns

[__JJ__]

This works great on the original theme unless you have sub forums in one main forums, but not all in the same category, then throws it all out of whack. You would need to have sub forums in all or no sub forums showing to keep them all the same size so it looks right. Wondering if is any way to fix this? Am wanting to use this on Duende & maybe Revoulution Gaming (I know it needs major edits to work on a dark theme) so any guide is appreciated.
