Simple Questions about README

[fnatter]

Dear Developers / @vladislav-yashin ,

many thanks for developing this very useful plugin!

I have some very simple questions [1] about usage of this plugin
in redmine 4.0.2 (the first two questions are most important, please
answer these!!):

• will (manual) installation of this plugin prevent future updates of
  redmine (i.e. 5.x)? Is it possible to disable the plugin if it does
  not work after an update?

• I think I shall run all commands as root (my /usr/share/redmine
  = {REDMINE_ROOT} is root-owned), even if redmine runs as www-data
  (Debian/Ubuntu package)?

• feedback: the schedule buttons are only there when logging in as
  admin user, is this intended?

• feeback: I made it work by checking [x] anonymous user in the prefs,
  and of course anon needs access to the project (this is missing in
  the readme); Also there is a tz/CEST issue: if I schedule at 0:00
  it runs at 01:00.

Or is there another project that has similar functionality and/or forks this one?
