For Gnome/Mate users, Ulauncher need less dependence.
Except for this, Albert is better.

What can this do that Albert, which we already have in the repo, can't do?

@yelf Why would you trust this company with your data?

Seems they just release new packages for Windows and macOS every several month, but no package for Linux. Don't know why.

And I found that I'm actually using the v1.5 on Ubuntu 17.04. Ubuntu package maintainer just packaged the latest github source for every Ubuntu release.

That's really kind. Could this possible for Solus.

The source code has moved to Github, and the development is still very active. Though I don't know why they haven't make a new release for 7 years.

Also I use Goldendict everyday(on Ubuntu 17.04) and never have any problem, and gnome-dictionary is by no means comparable to Goldendict.
So, I still think this package should be added. Please reconsider this request.
