Hello forum,

I've already submitted these features to the mailing list:

  https://lists.gnu.org/archive/html/emacs-orgmode/2020-09/msg00628.html

But even if these changes are really tiny and minor, they are touching very 
different functionality of org-mode. It wasn't good mixing my suggestions for 
agenda and for ox-icalendar. So I'm starting a separate mail thread for my 
suggestions.

Changes since v1:
  - Add missing group and type to org-icalendar-*-summary-prepend defcustoms;

Kind regards,
Mikhail Skorzhinskii

Subject: [PATCH 2/2] ox-icalendar.el: introduce setting to force alarms

This is a new setting for icalendar exports to allow users set alarms
exactly at the event start. With this setting set to non-nil and alarm
set to zero (by global setting or APPT_WARNTIME property) it will create
an alarm at the event start.

Note, that zero alarm set as APPT_WARNTIME property will override
default warning time.

Subject: [PATCH 1/2] ox-icalendar.el: allow to customise deadline and
 scheduled items summary

In some of export schemes these cookies at the start of each event can
be a distraction rather then storage of useful information.
