Well, I can honestly say that "Greatly-enhanced mobile-friendly style" scares the hell out of me. Most of the tapacrap forums are more difficult to navigate in mobile mode. Maybe I'm becoming an old crust f__k, but i don't mind zooming in to see something.
On a related note: what's up with the Pinterest link on embedded pics? Sometimes you can tap a pic and it blows up, but you (I) can't close it. I have to hit the 'back' button, then you're back in the forum not the thread.
That's for the default skin, the one I'm using should remain mostly like it is now just updated for 2.x and with more mods by me, I will test the crap out of it and make sure it isn't really weird and wacky.
I forgot about the pinterest thing. I wonder if anyone actually uses pinterest. I don't. I should probably get rid of it. seemed like a good idea at the time. See if anyone notices its gone lol.
re: the images, It probably depends on if its an attachment or inlined from somewhere else, etc. The pinterest button shouldn't affect that, unless you click on the button.
