Can be set through environment variable WIKIROOT. By default points to
~/Nextcloud/Notes/ but is kept configurable for each computer. Will be
picked up by vim wiki plugin to enable wiki functionality for the
respective directory.
Should start x after all the XDG folders have been set so that aliases
etc should still work. If binds/aliases do not work (things like tm, tl,
cl and so on) then this is presumably caused by a race condition and x
should only be started *after* all directories have benn set.
