Let helm-dash sort results by name of matched

[kidd]

seems like a good idea. for how long have you used this variant? (I guess in general it gives you more meaningful results, but just want it to be a bit time-tested).

I'll use this version a few days and merge.

Thanks!

@kidd I use this variant about one month, my several friends told me it's more quickly for find results use this sort way. So I create a PR to you.
