Maya 2011 lets you choose between two different "Dialog Styles" for interacting with the file system.
This one, called "Maya default"
or this one called "OS native"
This is the UI you see when you do things like open or save, import or export a file. The default (called "Maya default") lets you do more than just choose a file, and some people will probably find the extra capability quite useful. But I'm not one of those people. I prefer the "OS native" style of dialog. I prefer it because it is consistent with most other applications. Its great to have the choice to use one or the other.
What's not so great is that the OS native dialog does not correctly filter the file list... (more...)
