I've used future versions of Visual Studio for years

At least, that's how I've convinced myself to think about it. 

What I'm referring to is the large number of extensions I've built for Visual Studio and how, slowly, many of them become built-in features of the product itself.
It's not that my past effort has become unnecessary. It's that everyone else is catching up.

Visual Studio version 17.12 is now out. At the top of the list of new productivity features is the ability to copy just the description from the Error List, by default, rather than the full row.

I have an extension in the marketplace that does this. It's called ErrorHelper & it's been in existence for more than five years!

My extension also does more!

It allows searching for the error message/description (in the search engine of your choice) directly from Visual Studio.
Yes, VS now makes it easier to copy only the text of the description, but without my extension, you still have to go to the browser and search engine and paste it there. Or you could do it in one click.

As some error descriptions include file paths that can impact results or be something you don't want to share, there's also the option to do the search with the path removed. No need to manually remove the path from the text you've copied.

Additionally, as some error descriptions include a URL to get more information, you can directly open the URL in your default browser. No need to manually extract the URL from the other text and then paste that into your browser.

Having the Search and Open URL features has made me feel more productive every time I've used them. Yes, working with error descriptions isn't a massively complicated process but it previously felt slow and frustrating. It was a "paper-cut" that interrupted my flow and felt like more effort than it needed to be. That's why I first made the extension.

It's great that this feature has been added to the product, but it's sad that Microsoft has only gone so far.
They've said that they made this change in response to listening to feedback from developers who have told them that it was harder than necessary to search for error messages with the old functionality.
What has been implemented seems like only part of a solution to that problem. Copying the text to search for is only the first step in searching for an answer. Were they really listening that closely to the real problem if they only implemented half a solution?

They've also said that when choosing which features to add, they avoid adding things that are already possible via existing extensions. However, in their examples of this, they only mention existing extensions that were created by Microsoft staff. I guess my extensions don't count. :(

I also have many other extensions available in the Visual Studio marketplace that you could begin using to improve your productivity now rather than wait for something similar (but possibly not as good) to be added to VS itself.
