TL;DR: Boost your productivity with the Slidepad app, which is on sale for 25% off. As of July 10, get a lifetime subscription for only $8.99.
Slidepad, a highly-rated Mac app, can help you multitask like a pro and boost your productivity.
Rather than constantly clicking through tabs and minimizing and maximizing windows, Slidepad changes the way you open things. It’s in the form of a browser that pops up whenever you hover to the side. That’s where all of your essential apps, documents, and websites are waiting for you — and you can use any of them without crowding your screen or slowing down your flow.
You can customize your Slidepad with all of your most commonly used apps or documents, or specifically for whatever you’re working on at that moment. There are no limits on the number of apps you can add — the pad will simply expand according to your needs. You can even customize your notifications and sounds throughout your sliding experience if you wish.
It's regularly just $12, but you can snag a lifetime subscription for even less — $8.99 — for a limited time.
