Fix the issue "DataGrid scrolling glitch where only some DataGridRows have a visible RowDetailsTemplate" documented here:
I have a DataGrid with RowDetailsVisibilityMode set to Collapsed. In the DataGrids LoadingRow event, I look at a property of the DataRow's bound DataContext and choose to set the DetailsVisibility of the DataRow as appropriate (eg. show some error details in the DataTemplate if the bound item indicates that there are errors, otherwise keep the DetailsVisibility to Visibility.Collapsed).

Windows 7 Phone has a built in word dictionary for the keyboard. Please expose some APIs for looking up words.

there is usually a requirement in most of the text boxes to show a watermark or some text that shows what should appear in a text box. This is termed as QueryPromptString in a share point search box control. A similar functionality I expect in silverlight text box as well.

Let the SL Plugin be a basic download of 4-5 MB which enables basic support for SL

then let developers define modules which is needed to run an application.

eg:
- "You need to download the 3D Module to run Crysis.XAP, click OK to download 10MB Module"

- "You need to download the AntiVirus module to run Norton.XAP, click OK to download 15MB Module"

Increase the DATAGRID_maxHeadersThickness = 32768; For LOB apps hundreds of columns are sometimes necessary (to render data which might ultimately be exported to Excel).

so that let a pureness sl app more like a general web app,have more html can between jump eachother ,
if apiece xap more small then user wait time is more short,
I don't know that this idea is appropriate

It will be great to have default converter from bool to visibility. All we use it in our applications and why erite the samw converter each time?

This way user can get the previous version if the new one breaks some old functionality
