[Orgmode] Multiple column views for one file

[Thomas Leitner]

Hi,

I don't know if org-mode supports having multiple column views for one
file currently but I did not find a way to do the following.

What I have is a journal file in org-mode in which I record, for
example, films I have seen, books I have read and kilometres I have
run. All of these entries have properties based on their type, for
example, films have the properties Genre, Year and Director. Now I
would like to get a sparse tree for all entries tagged with `film` and
use a special column view for the films. However, when I define the
#+COLUMNS variable at the top, this procedure only works for films, and
not for books or other entry types which have different properties.

Therefore it would be nice to be able to define several column views
and the possibility to switch between them. It is currently possible to
disable column view by pressing `q` when the cursor is on a head line
in column view. It should probably be no problem to add another hotkey
like `s` for switching to a different column view. The different column
views could be defined like this:

#+COLUMNS: films %70ITEM(Details) %TAGS(Context) %Genre %Year %Director
#+COLUMNS: books %70ITEM(Details) %TAGS(Context) %Author %Year %Pages

It seems that org-mode currently ignores the column view names ("films"
and "books") so this would be backwards compatible.

I'm still at the beginning of learning Elisp, so I'm not able to
implement this myself and would like to know if others find this
proposal useful and if it could be implemented?  

Best regards,
  Thomas
