@MartinR I've really got to keep that open in one of my 15 tabs! I find questions all the time, some that I even recognize as one I answered, and this site fails. Thanks again!
Approach0 is really great, and it helped me to find many duplicates. I wonder if there is any way to add "Search with Approach0" to the context menu of math formulas in the browser.
@amWhy @user21820, @Did, @SimplyBeautifulArt, @MartinR, @ZacharySelk, and many others. I have replied to the comment above this post, to note that the question I linked has been closed. It is now open for deletion. Thanks!
