Subject: Autocollapse of outline nodes
Date: Mon, 24 Apr 2006 13:15:03 +0100	[thread overview]
Message-ID: <3c12eb8d0604240515l3313b552o2ba25db2e7012f97@mail.gmail.com> (raw)

Hi,

Here's a small piece of code that periodically collapses all org nodes
(trees) which are far away (structurally) from the current cursor
position.  The purpose is to automatically collapse nodes which you
are no longer working on, thereby preventing uncontrolled growth of
the visible size of your .org buffer as the day progresses.

Please send your comments/suggestions, for example, whether this
functionality has already been implemented elsewhere.  Should work
with any outline buffer.

Piotr
