Update on HG Launcher work

I have made some progress on an issue: https://github.com/F4uzan/HgLauncher/issues/38#issuecomment-495471299

However, in testing I am finding that the keyboard is not displayed when you return to the search. I might file this as a new bug. Not sure.

I think I'll go ahead and do the PR since this is like this in the live version.
