I'm still thinking about this (and your response), and will be testing some things, then when I feel comfortable I'll be asking testers (e.g. you) if it works for them, since I only have a limited number of personal testing devices to test with. (test)
I would talk about it more but it's kinda difficult when you don't know what I've designed (the entire site is going to look very different), but in general I try to code things around being responsive, and yeah of course the sore spot is tables since it's ... tables.
I've thought about entirely redesigning tables to just be flowy grids instead, but that easily messes up genuinely tabular data, I know, which of course is what bbcode tables are supposed to hold, mainly.
I think, given the design I'm aiming for, its fine for the desktop to scroll horizontally, but it will break flow on mobile devices.
I just wanted you to know, since I'm back to work (thankfully), I'm still mulling over it. I know it's been a while (and I want them to work better too!)
