We have planned to have a preferences window, but we might end up not needing it. We’ll see.
We do have options for various things of course, but so far they fit very well in the menues.
One of the first menu items in the X-Sheet menu is for swapping sides, so the x-sheet goes to the opposite side (and the tool bar swaps side as well always being opposite of the x-sheet).
We might make them independent of each other in one of the next alpha releases.
