Elementary OS seems to support almost everything on the Asus TP200S out of the box, but one issue is screen auto-rotation.
Elementary OS recognises that the screen should be rotated when flipping the computer into tablet mode and back, but by default the screen is rotated sideways 180 degrees when in laptop mode. In tablet mode, the screen flips to landscape, horizontal mode (what I want in laptop mode).
Changing the GUI settings allows me to change the rotation manually. However, if I put the screen into horizontal/landscape mode, it will not switch to vertical mode when I flip it into tablet mode, even though I have rotation lock off.
Furthermore, the GUI settings never persist in the lockscreen. No configuration of the GUI rotation settings shows up in the lockscreen and it's always rotated 180 degrees in laptop mode (but it will flip into landscape/horizontal mode when I put it into tablet mode in the lockscreen).
