1. Sometimes I want all the subtrees of a tree to inheritance the
property "CLOCK_MODELINE_TOTAL" (e.g. all set to "today"), but in the
function *org-clock-get-sum-start*, you use (org-entry-get nil
"CLOCK_MODELINE_TOTAL"), which means that it doesn't search inheritance.
This makes the inheritance setting in vain.

    2. Sometimes I want to mark something done yesterday (e.g. I'm leaving
that night but still finishing the project without computer at hand). I use
*org-todo-yesterday*, but I find that if it has a *++ repeater*, the new
date begins *as if the task is done today*, which is not desirable.
