My Calva PR Checklist

I have:

• Read How to Contribute.
• Directed this pull request at the dev branch. (Or have specific reasons to target some other branch.)
• Made sure I have changed the default PR base branch, so that it is not master. (Sorry for the nagging.)
• Updated the [Unreleased] entry in CHANGELOG.md, linking the issue(s) that the PR is addressing.
• Figured if anything about the fix warrants tests on Mac/Linux/Windows/Remote/Whatever, and either tested it there if so, or mentioned it in the PR.
• Tested the VSIX built from the PR (so, after you've submitted the PR). You'll find the artifacts by clicking Show all checks in the CI section of the PR page, and then Details on the ci/circleci: build test. NB: There is a CircleCI bug that makes the Artifacts hard to find. Please see this issue for workarounds.
  • Tested the particular change
  • Figured if the change might have some side effects and tested those as well.
  • Smoke tested the extension as such.
• Referenced the issue I am fixing/addressing in a commit message for the pull request.
  • If I am fixing the issue, I have used GitHub's fixes/closes syntax
• Added to or updated docs in this branch, if appropriate

We should probably update the docs too.

Closes #852 as well. I don't think this comment will suffice to cause the auto closure.

[bpringe]

I tested the VSIX as well.

[bpringe]

Great idea making these configurable!

[PEZ]

I think you can edit the PR description, @bpringe . That might auto-close the issue.

[PEZ]

Added the docs, @bpringe . This is good to go, me thinks, especially since you've tested it too. However, family calls here. If you find some time, please merge and release.
