Hello,

I've attached a few patches for org-timer.el.

Some additional comments on two of the patches:

[PATCH 1/4] org-timer.el (org-timer): Recognize double prefix

    This patch makes org-timer behave as described in the docstring when
    it is given a double prefix argument.  However, I'd actually be in
    favor of removing this functionality from org-timer (and
    org-timer-start) since it's already available directly through the
    interactive command org-timer-change-times-in-region.

[PATCH 4/4] org-timer.el: Isolate commands of different timers

    This patch fixes several issues that were caused by executing a
    relative timer command when the countdown timer was running, or vice
    versa (see log message for details).  Perhaps it would also be
    helpful to make it clearer which commands belong to the two
    different timers.  This is clear in the manual (the relative and
    countdown timer have different documentation pages), but what do you
    think about renaming countdown timer commands to have 'countdown'
    after 'org-timer' (e.g., org-timer-countdown-set-timer)?

Thanks.
