This would be very useful to be able to force encoding on solution or project level and don't select it on per-file basis.
This would be great feature for internationally distributed developer teams and for open source projects.

Bring back VS Studio Express Web 2010 - "Add Style Rule" - for 2012 edition - cannot believe you intentionally dropped this feature.

When you are in a aspx.cs or ascx.cs files, you can do a rightclick en click the "View Designer" (Shift+F7), but better is to view its code instead of opening the designer, please add this option or alter the "View Designer".

Since the new Visual Studio has a lot less color, I don't mind BUT my tabs look all the same and miss some visual structure.

Maybe it would be nice to assign you own colors to your tabs, different colors for pinned & not pinned- states or different colors for each project!

Close all tabs to the right of the selected tab. This is something I love in the chrome browser. Combined with allowing to move tabs around, it's an efficient way of getting rid of clutter.

In VS2010, in the Team Explorer view, you could right-click on a folder or document and see the properties of the folder/document, which included the path to the folder/document. This was immensely helpful and needs to be put back in the VS2012 Team Explorer view.

Currently you offer shortcuts for switching between active documents via Control + F6 or Control + Tab. However, for those of us who lay out our documents spatially, cycling through documents in all tab groups when we just want to get to the other visible document isn't an ideal scenario, and really breaks our flow.

I'd love for Window.NextTabGroup and Window.PrevTabGroup actions to be added so I can quickly hop between editors.

Currently the Forms Interop Toolkit plugin http://www.microsoft.com/en-us/download/details.aspx?id=3264 is supported up to Visual Studio 2010.

My company is currently migrating our flagship product from VB6 to VB.NET and we wanted to use the Forms Interop Toolkit to help us do this gradually however we want to use Visual Studio 2012 which is currently not supported by the Forms Interop Toolkit plugin.

Please add an option to search for files (actually the filename) in the current solution, from Quick Launch.
I keep Solution Explorer closed most of the time, and I really enjoyed opening a file form the search box via ">of Filename".

You should can connect your Visual Studio to your live account. Visual Studio should save the settings to the account. If you now use the Visual Studio on another computer you only have to log in to your live account and then the settings of visual studio will be loaded automatically from your live account.

Search in files only supports two windows for search results. Old results are permanently discarded and new results are displayed in one of the two windows.

Add support for multiple search result windows.

Being able to drag windows onto a split screen separate from the source windows hosted on the main IDE has improved developer productivity. However, it becomes troublesome when you have more than one source window on the split screen since it does not cater for docking of the floating screens into another tabbed MDI structure. It would be nice to be able to have tabbed MDIs on both screens to make navigation easier.

As a former Borland Delphi developer, I miss a simpel function in the VS IDE.
In Delphi you are able to [Shift]+Click a control in the ToolBox and this control is now locked so that you can place several controls on the form, simply by clicking the form.

This makes it very easy to place a lot of similar controls, like labels or textboxes, on the form.
The control is released by clicking an arrow icon afterwards.

Please put the menu in the top bar as in the attached screenshot or make it only visible when the ALT key is pressed. As example, please see Firefox 12. It uses minimum height for the menu and the top level menu (file, edit etc.) is only visible when alt is pressed. it is also a setting so, if users want it permanently visible then can check a box.

Pretty self-explanatory. Make the IDE able to open a "Go To Definition" request in a new tab so that the current tab remains at the current location (making it so that you can easily find definitions for multiple items without loosing your mind).

Today, if I create solution folder, it is not mapped to the physical folder on my hard drive. Than, if I want to add project into the solution folder, I always have to validate the path, where the new project will be added. In my case, I always wants to have the same physical folder as the solution folder. Turing the creation new solution folder it should be possible to choose, if it will by physical folder or only virtual solution folder (like today).
