Adapting the current default demo to that would take too much time and I have almost none currently
... still, since it is Christmas I can give you three possible alternatives:
1st) use the imode reducer version
, which completely sucks and is nothing of what you're expecting.
2nd) is to use a different theme. I've spent sometime adding a new theme to the forum which is responsive. It is different (even the colors, it is light) but at least it adapts to your screen size. You can give it a try by going to Profile -> Modify Profile -> Look and Layout -> Current Theme: (change)
, but I'm not sure you will adapt or even like it.
3rd) use an app in your device. There is an app called Tapatalk
which I never tried but know that it serves to view forums. If you wish I can try to install support for it here and then you can check this and other forums in that same app.
What do you think?
