The best feauture of iSlide is the extended toolbox that saves time when designing presentations, many aren't even aware they exist in PP whatsover!

The design looks much better than in Power Point. Things don't collapse when you move a picture or 2. In general when you work in it feels like it's smoother.

iSlide is a feature-packed PowerPoint add-in that makes designing slide decks easier for both professional designers and novices alike (that's me). With iSlide you have all the pro tools that are normally tucked away somewhere in PowerPoint right where you need them the most. iSlide's tabbed interface blends in very well with Microsoft's ribbon UI for Office programs and this makes it very intuitive. Making quick design changes is easy and straightforward. Additionally, iSlide adds a tonne of useful resources that should help anyone upscale their presentations with ease. Last, and probably best of all, the free tier allows newbies to dive in and test the tool before committing to a long-term plan and it is a fully functional free plan for most of the essentials.
