Not a SnippetsEmu related post but hopefully of use to some Vim users.
I use the Project plugin (get it here) to keep track of files that I'm editing. It's a great little plugin though is a bit flaky under Windows (there's some problems with the way it constructs paths which affects some of the nicer features such as greping and auto entry completion)
One thing I've just noticed, however, is that one can trip up when using the CD property. When set the current working directory can be changed when opening a file. I normally set this to be CD=. which will CD to the directory in which the file is located. The problem I've found, however, is that you can end up overwritting files when you split the view (as I did with snippetsEmu). My tip for avoiding this is to set the CD at a suitably high level. I've set mine at the root of each project. This allows files to be saved but stops the status line from getting too cluttered.
Hopefully someone finds this useful.
