Maybe this will help you with your decisions. I am not sure, but well...xnview wrote:(...) By using tabbar at the top, i think that it's better. (...)
1.) Mouse movements; It is always easier and faster to move the mouse UPwards, because an upward flick with the wrist away with the arm in a lying position on the table is naturally easier, than to pull it back towards the position of the arm. Try it for yourself, you will see, it is harder, and not so good to control than any upway movements. Therefore, placing menues at the top of an application of the screen (yes, also the Win-Taskbar/Startmenue), will always grant faster access of buttons, tabs, etc..
2.) The eye; Looking upwards with the eyes is also more "natural", aka. more precise than looking down. Don't ask me why. Maybe thousands of years hunting mammals helped a lot. Try it. Try to find something on the lower place from your screen, maybe after you typed something, and than on the top of the screen. Should at least be more precise (and quicker) to find something with your mousepointer, though.
To sum it all up, I would love to have the toolbar more on the top.
Maybe this was of help.
