I've been using Ubuntu for a while now, and updated at the last update to use unity. The last time I had updated I tried unity and didn't like it because it slowed my computer down a bit (it is a low power computer, similar specs to a laptop I guess). This time, however, it wasn't slowing down my computer noticeably, so I continued using Unity, looking for a couple of tweaks on the way.
One thing that I didn't know how to do initially is was how to move things around on the dock on the left hand side. When I was using the old version (Classic I think it was called), I had some application links on the top bar, which were automatically transferred over, which was handy. I tried dragging them up/down to reorganise them, but that didn't seem to work. I eventually figured it out - I had to drag them outside the dock (i.e. drag them out to the right away from the dock), and then I could move them up and down. Not as obvious (to me anyway), but I figured it out in the end. Thought I would post it here in case someone else is trying to figure out how to do it.
Overall, I'm not that bothered about Unity, and don't mind using it. Its alright and now I've used it for a bit, I've gotten used to it. Still haven't figured out how to move the 'close' buttons to the right hand side of the top toolbar (they are on the left by default) - I can change it for when it is minimised, but not for the maximised window, which uses the top toolbar (which is a bit weird, but OK).
