[Orgmode] Remaining time (in column view)

[Daniel Clemente]

  Column view (C-c C-x C-c) is useful to show how much time I have estimated 
for a task and how much time I have clocked for it. It also seems helpful to 
show „how much time it remains“, which is the difference {estimated time} - 
{clocked time} for that task. It can be positive, negative (overrun) or empty 
(if you didn't estimate the effort). It is useful to choose the next task to do 
from a set of partially worked-on tasks.

  Just like there is a special column called CLOCKSUM ([1]), ¿is there 
something like CLOCKREM to show the remaining time?


Thanks,

---- Daniel
