- I often have to edit or create vector graphics in Adobe Illustrator but don't enjoy using it. It's more than powerful enough, but it's a bit slow, it doesn't respect much of the macOS UI stuff (fullscreen, versioning, iCloud etc.), slow start and that it installs a lot of other apps, Creative Cloud stuff etc. And have it's own software update system. In fact I don't like the entire Creative Cloud solution, but for the other apps I use Sketch + Pixelmator.
My reading and listening skills have improved so much since using Duolingo, I couldn't recommend it more. I'm not naive in thinking it will make it fluent as it's not the best for speaking skills but has vastly helped me improve and build up my language confidence.
I listed "gem restrictions" because I would like to use it without limitations, but I understand that it is part of their business model.
