We wanted to but nothing really handled tokenization well. In the end we wrote our own (which is why there are various caveats).

For other things we're using select2. At one point we had tried to switch to selectize but we found limitations in its API and frankly didn't want to spend the time to find ways to work around them.

Did you try: https://documentcloud.github.io/visualsearch/ ?

Nope. I don't think we were even aware of this project. It's pretty slick; I'd probably experiment putting it into Sentry.

Hey, I wrote that widget! I'm also a long-time Sentry user and would love to see VisualSearch.js integrated.
