Follow option should view the opened file centered vertically, `zz`

chadtree_settings.options chadtree_settings.options.follow CHADTree will highlight currently open file, and open all its parents.

When I open a file that is below the viewed part of the files (below the viewport), the cursor goes to focus the opened file but it will be in the last line in the CHADtree window, I suggest using something similar to zz make the line at which the cursor is at the centre of the window vertically
