Hi, I'm Go - Programmer / Co-founder of an indie software maker Plastic Software.
We have just released Haste, a Mac App that accelerates your daily web searches, saving you valuable time.
Please get it from the Mac App Store, by following the link on the site:
(Compatibility: Mac OSX 10.11 El Capitan or above)
The product version of the app is a freemium (Free Version -> Unlimited Version via In-App-Purchase).
You can use the full (Unlimited) version with 14-day trial period.
After that, you will still be able to use the app for free with limited number of Custom Searches available at the same time (Please see the app descriptions for the details.)
Please check it out if you are interested. Thanks for your time and attention!
