I've been using Hain for the past 6 months, it s great but again built with Electron and can be a memory hog. Also the developer has seemingly become quiet in the past few months. I'd pay for a Alfred type windows version.
Thanks for the suggestion! Unfortunately, it's also an Electron app, which is something I would like to avoid. If footprint is also a concern to you check out http://keypirinha.com! It's really great, with the only concern being not very elegant aesthetically...
Just installed Keypirinha. It's great! Thanks for the hint.
