By default, LinqPad imports several namespaces (System, System.Linq...) and references several assemblies (System, System.Core...). This is fine in most cases, but sometimes I'd like to be able to remove some namespaces or references, and currently there's no way to do that. These default namespaces and assemblies should appear in the query properties so that they can be removed (it could be an option for users who don't want that)

Just like in Visual Studio (and MANY other editors):
When you select some text in the editor, the same text gets highlighted. This helps the developer identify errors and places that needs to be changed / refactored etc..

For long-running queries that call Dump multiple times, it would be good to have the results from the earlier queries show immediately rather than waiting for the whole query to complete.

Add so that you can set the results in different monitors. Would be very nice when the result is very large.

When Linqpad first starts, it automatically connects to every server you have added as a connection. Please add an option to disable this behavior and only make a connection after clicking on the server first.

Upon detecting multiple statements: Automatically switch Language from Expression to Statement(s) for selected language.

Many code editors use Ctrl-Shift-U to toggle the case of selected text to upper case.

It's faster than alt-F4, and works in many other applications with multiple tabs.

Would be cool if we could share queries to frineds through instant messaging in a similar way that Small Basic does it:
http://blogs.msdn.com/smallbasic/
it will store the query on a server somewhere and give a short link you can hand out for people to use.

It would be great to have the ability to choose a version other than the latest version of a Nuget package. Oftentimes, we find that latest versions of packages can break functionality or we are just not ready to move to latest version of package yet and we are not in control of the Nuget package itself.

I would like to be able to add Nuget reference and optionally supply a specific version string (it can be manual entry and not a list).

As in VS WPF design.code window panes, I really like to have the ability to create vertical panes for coding and results whenever I want. Like to press some button and change their orientation from Horizontal to vertical or vice versa.

Support Entity Framework Core RTM, which is not EF 7.

Instead of a new tabs always being named "Query n", allow the tab to be renamed without saving it to a file first. I think it would also make sense to not allow renaming of a tab from a file that was loaded.

I'd like an option for line wrap in the text editing pane. Other text editors have this option (notepad++, visual studio)

Allow upgrading LINQPad NuGet package to 3.0 independently

When using a DbContext for a connection, LINQPad currently only supports parameterless constructors or constructors accepting a string. Please consider supporting IDbContextFactory<TContext> with Entity Framework POCO connections.

SQL Azure won't allow you to use the same methods as an onpremises version, so it currently fails on connection. However, fundamentally it is SQL Server 2008 under the covers and would be easy to support. This would be the best cloud database mgmt tool.
