I have a custom Fluent theme as a package, it would be nice if there was a way to load packages (Embedded Resource or files) with the RadThemeManager.

Rather than typing this: Telerik.WinControls.ThemeResolutionService.LoadPackageResource("GUI.Themes.Fluent_Custom.tssp");

Right now the RadThemeManager only supports XML files. Feeding it a tssp file doesn't work.

For it to show up in design-time I have to assign it all of the unpackaged XML files and then delete the RadThemeManager for the theme to show up, otherwise the load time is like 7 seconds, where as embedded packages load super fast.

The fluent theme has a lot of XML files and this is a huge pain, supporting 1 Embedded Resource tssp package would be nice.

Would also be nice if the RadThemeManager could apply/change a theme globally somewhere in the SmartTag menu or RadThemeManager properties.

Instead of having to type this: ThemeResolutionService.ApplicationThemeName = "Fluent_Custom";
