Ctrl+Shift+V is nice for when and where it works.
Would you rather prefer Ctrl+V to paste unformatted text by default into any Windows app?
I personally think I want this behavior by default, and I could add this feature to DevComrade
(free and open-source), if there's enough interest.
If you feel it's a good idea, please upvote this DevComrade
issue, discuss it here or respond to my original tweet.
