Can I share settings for IntelliJ Idea across different projects?

In the month or so that I've been using IntelliJ, I have one project that I am working in the majority of the time in which I have all of my windows, toolbar locations, etc., set up to my liking. I infrequently need to open other projects in IntelliJ, and I notice when doing so that all of the window locations seem to reset to the default. For example, the Structure toolbar moves back to the lower-left hand of the screen; I prefer for it to be docked in the upper-right hand corner. Can settings for window and tool locations be shared across different IntelliJ projects? Can I configure this once globally, and have it apply to any new project I open in IntelliJ going forward? Also, does anyone know where these types of settings are stored - I assume it's in the per-project IntelliJ files (such as `.ipr`, etc) rather than my global `.settings` directory?
