Auto-compile & IDE-level tool window settings

Hello everyone,

I've just started using the Intellij IDE for about a week now, and so far loving it very much (using it for Java development). I've got a couple of things that I'm still not sure how to get to work as I'm expecting in IDEA:

1) Is there a way to make Intellij continuously look for compilation errors and identify files that failed to compile in the Project tool window? for example:
If I have a file B that uses functionality in file A. If then I remove said functionality from file A (manually without refactoring), shouldn't the project file show that file B no longer compiles?
It only realizes that file B contains errors and marks it accordingly in my Project tool window if I open file B afterwards in the editor.
I have auto-compile turned on, but it doesn't seem to help with such scenarios. What am I doing wrong?

2) Is there a way to ingrain my tool window settings at the IDE level? I would like to keep how I set the tool window's size/docked/pinned/etc between projects, so if I create a new project I would like it to use the same settings. Is that possible for tool windows?

Thanks
