Don't know if this is worth mentioning or not, but... I know that the mobile version only allows the sidebar to be viewed in portrait mode. However, I have an Asus Transformer TF300T (Jelly bean) with the keyboard dock. When docked, the screen rotation is disabled and locked into landscape mode. So, the sidebar becomes totally unavailable unless I take the thing out of the case and undock the tablet.
I understand that I'm in the minority with this issue, but I at least wanted to bring it to someones attention since tablets are becoming so popular. It would be quite helpful if at some point the option was there to view and scroll the sidebar in landscape mode.
Thanks
