Today was one of the days when I found a feature in Visual Studio which could have helped me already years ago.

If you’re working with many tabs (like for migrating something) you find yourself searching the right tab quite often. To solve this, there is a (for me unknown) setting in Visual Studio to move pinned tabs to it’s own row in the Document Well.
See the following screenshot for this setting:

Sometimes, if that is not enough, there are Add-Ins available to go further with that.
One is Productivity Power Tools which is free and enables also other possibilities for the tabs.

Then there’s also the commercial Tabs Studio which should provide pretty anything you need.
