How to Make Visual Studio Really, Really Responsive

Turn off ReSharper.  So far, I miss it not a whit.

Configuring Visual Studio 2010's Tooltip Colours

This has taken some finding.  First, install the Productivity PowerTools Add-in.  Then go to Tools > Options... > Environment > Fonts and Colors > Text Editor and change the settings for the Signature Help items.

Making things stretch in WPF

I quote from a StackOverflow reply by one Matt Hamilton:

There are also some properties you can set to force a control to fill its available space when it would otherwise not do so. For example, you can say:

HorizontalContentAlignment="Stretch"

... to force the contents of a control to stretch horizontally. Or you can say:

HorizontalAlignment="Stretch"

... to force the control itself to stretch horizontally to fill its parent.

That should come in handy in future.
