1. Find a way to add new objects into BED editor (scenario/campaign editor).
http://eech.robfox.net/utils.html
Currently object list is closed and new added objects to game code can't be added with editor
This can really improve quality of maps.
I tried to contact BED maker years ago - no success.

2. Upgrade of existing tool to place trees on map. I'm not programmer and it's hard to me to uderstand how it works.
It's included in source code pack at:
http://chambcra.freeshell.org
It was designed to work with grand canyon map but maybe will be possible to use it for any existing map.
I tried many times to usethis tool - only thing I can acheive was trees floating in air.
