It would be great if the Ctrl+E SSMS shortcut would be enabled as an alternative to F5. It's easier to reach and makes sense (E for Execute).

In SQL Management Studio, you can use expressions like

DECLARE @FirstName NVARCHAR(max)='<Enter FirstName,nvarchar(max),John>';
DECLARE @LastName NVARCHAR(max)='<Enter LastName,nvarchar(max),Doe>';

in a *.SQL file. When you press Ctrl+Shift+M, then you are prompted to enter the parameters in one single dialog (in this case it shows "Enter FirstName", and "Enter LastName" displays default values "John" and "Doe", both of type nvarchar(max))

This is quite useful to have some quickly generated macros at hand, and maybe the idea could be supported in C# for Linq Expressions as well ...

Similar to the great new Shelve feature and combined with Named tabs I would like to be able to save my open tabs and give that group of tabs a name and be able to re-open them together. When working on projects I often have several related tabs open and when I go back to work on that project again, I often want all the same tabs so it would be great to be able to reopen all at once. A file that just opens other .linq files into their own tabs.

The debugger in LINQPad 4.5 is awesome, but not as good as Visual Studio's. Before the beta, I was using Debugger.Launch/Break to debug in VS. Now, those launch LINQPad's debugger. Unless and until the debugger is as good as VS's, I would like some kind of button or something (as long as it's faster than using the preferences) to use an external debugger.

Obviously, features new to 1.7 (and later) will not be available as LinqPad seems to reference the 1.1 version. Also, I've been having this issue:

Assembly 'MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'Microsoft.WindowsAzure.StorageClient, Version=1.7.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'Microsoft.WindowsAzure.StorageClient, Version=1.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

Yes, we can add a new folder via save dialog but it will save time

Provide more information about thrown exceptions (dump message, stack trace, etc).
