Thanks for your feedback Batsu!
A tabbed-style Browser: coming soon. It will also have a dropdown for those frequently visited EQ2 sites.
Hotbars: easiest to move by right-clicking and opening the Hotbar Settings and then enabling Spinners. With spinners enabled, you can click and drag from the Number Bank (then disable spinners later). I too just drag the borders to reposition them.
Glad you like everything so far!
