I see what you are saying "tgkeul", but I don't prefer to work on projects this way.
I prefer to look through the folder tree in the project pane and create the files / folders.
Also, I just noticed, if I use the open dialog to create a folder, if doesn't show up in the project pane, I need to refresh the project. This is a huge pain the butt because if I am 3-5 folders down (sometimes even more), I need to point and click about a dozen times to get back where I was. The same goes for creating a new file. It takes a major hit in my production time!
One last thing I noticed, when I create a folder and it doesn't contain any files, the folder doesn't show up in the project pane...
So again, its nice to see this in the beta phase, I just hope to see it touched up a bit - its still very buggy and not workable with at the moment.
