Favourite Adobe app
The problems that I have been solving are mostly client based - they have needed high quality designs for their content. I have been to be able to create sophisticated illustrations and infographics for the content, in a range of styles. I work a lot in content design, elearning and information architecture and knowing this software gives me an edge over a lot of my competition in producing better visuals.
The integration with other CC apps and crossover of some effects in the most recent versions. I prefer to work in vector than pixels and this is the most usable app to do so. The newer features like 3D effects, asset export are great developments that make it much easier to produce illustrations and export them. The programme is intuitive to use due to the layout and structure being similar across all the CC apps.
I struggle to keep up to date with new tools and tricks, and to have the time to experiment or work out how things work. You need to do things frequently to remember how to do them. I often just end up relying on the stuff I already know.
