[TxMt] Project expanded/collapsed folder state

[Kevin Tran]

I am working in a project that has many folders corresponding to real  
directories.  After working for a while, there may be some folders  
that are expanded and others that are collapsed.  The thing is that if  
I close the project and open it again later, then all of the folders  
will be collapsed.  This is very annoying because I must expand all  
the folders I want access to every time I work on the project.  Is  
there a way for TextMate to maintain the state of which folders are  
expanded and which are not the next time I open the project?
