Tried to use the TODO bundle and it was taking an age (10s of seconds) to give me a result. Some puts in the command code showed it was parsing all the text files in the directory and sub directories that the project file resided in. These files are a super set of the ones in the project draw - I only expected it to search in the project specific files. As a contrast using the 'find in project command' to search for TODO returns instantly.
