I see that there is no progress on the Status bar.
We are looking at converting from a competitive product for WPF to get some synergy/Look and feel between our Silverlight apps (these use Telerik Silverlight controls) and WPF apps.
I realise that in-browser apps don’t and should not use their own status bar but WPF desktop apps need a status bar.
Without a resolution to this problem we cannot build an application that ‘looks right’
All you major competitors either have status bar controls or panels that support theming and allow you to build themable status bars.
IF you do not intend to develop one then perhaps you could suggest how you would go about building one that does support your theme manager.
