A quick shell script to automate removing DropBox's green tick icons from the finder (they come back whenever DropBox updates itself, so automating removal is handy).

hide-dropbox-ticks.sh

#! env zsh

# This script turns off the annoying green tick-marks dropbox overlays on all
# files in it's directory in the finder. It involves making changes to the app
# package contents, so could cause problems for you (although I use it without
# trouble). You have been warned.

cd /Applications/Dropbox.app/Contents/Resources/

if [[ -f emblem-dropbox-uptodate.icns ]]; then
    killall Dropbox
    mv emblem-dropbox-uptodate.icns emblem-dropbox-uptodate-do-not-want.icns
    killall Finder
    open /Applications/Dropbox.app
elif [[ ! -f emblem-dropbox-uptodate-do-not-want.icns ]]; then
    echo "Tick icon not found"
    echo "I coundn't find the default tick icon or a disabled version."
    echo "Something's up..."
fi
