You asked for it and Microsoft has listened! Dynamics CRM 2015 now provides the ability to launch the Advanced Find window from anywhere within the application.
Previously, the Advanced Find button was only available on the command bar (or in the overflow menu) on forms and views which was a bit of a nuisance and required a few clicks just to launch it.
An important thing to note is that when you launch Advanced Find from a form, it opens in a separate window with no minimise or restore buttons. You also cannot click back onto the main window to navigate back to the form.
Launching Advanced Find from within a view yields a different result. The window that opens allows the user to minimise and restore.
Having Advanced Find globally available is one of my personal favourite features of the new release. Stay tuned for more new features in Dynamics CRM 2015.
