Setup to use it together with UndoTree

UndoTree layouts use absolute positioning commands by default (topleft,botright) but it can be configured to accept custom ones. (stackexchange)

" === UndoTree
" using relative positioning instead
let g:undotree_CustomUndotreeCmd = 'vertical 32 new'
let g:undotree_CustomDiffpanelCmd= 'belowright 12 new'

" === Goyo
" changing from the default 80 to accomodate for UndoTree panel
let g:goyo_width = 104
