Here's what I just posted as a comment on that issue.  It's in core,
not a plugin.

Not sure the headline abbreviation thing really addresses the OP's
idea, although it could make @clean appear as @fileclean when not being
edited. But for newcomers, that might be more confusing than helpful -
if they started entering @fileclean. It's more typical use is to make
@clean appear as an icon, a document with a C on it, to reduce screen
space use by directives like @clean. Maybe that addresses the OP's idea
as it's a file icon.

Here's instructions for using it I wrote in response to a recent
question:

Search for tree-declutter in leoSettings.leo.

set

@bool tree-declutter = True
then craete a @settings node

@data tree-declutter-patterns

can contain patterns like:

# remove @clean and use an icon
RULE ^@clean (.*)
REPLACE \1
ICON file_icons/file_clean.png

# show the last part of long filenames
RULE ^.{1,1000}([/\\])(.{25})
REPLACE …\1\2

# if the node name starts with 'peacock node DEMO', make a mess of it
RULE ^(peacock node DEMO)
REPLACE LOOK: \1
ICON Tango/16x16/emotes/face-grin.png
ICON Tango/16x16/emotes/face-wink.png
FG @solarized-magenta
BG white
FONT Times
PX 40
ITALIC 1
WEIGHT Bold
