Q: Mark or highlight files in Visual Studios Solution Explorer is there an Add-In which allows me to tag or mark files in Visual Studio and then these files are visual highlighted (eg. different background color) ?
I searched the Visual Studio Gallery but didn't find anything.
Thanks!

A: I found the extension Visual Studio Tags on codeplex that can do what we need, but there's not (yet) visual support (ie, diferent colors in solution explorer).

A: To highlight only the active (open and viewed) item in the solution explorer (without any add-ins):
Go to Tools -> Options -> Projects And Solutions
Then Check the Track Active Item in Solution Explorer option.
But if you really want to use any extension in order to mark the files you already checked/reworked so that you get an better overview or whatever then I would suggest ReSharper which has a number of features assisting navigation and search.
For example, there is a To-do Explorer which helps navigation between to-do items within the solution. You can also create custom filters in Resharper To-do Explorer. After creating custom filters according to your need, you will have to leave comments wherever required but you won't have to open all the files to read the comments.
