It’s a relatively simple-to-use presentation app, but has really useful features like pattern and gradient backgrounds, rich image, graphic, and text support, and PDF exporting.

Tomato

While a pomodoro app doesn’t seem like that big of a deal, Tomato (whose development is lead by Luiz Augusto) is a great little app that does exactly what you’d expect while fitting into elementary OS. It also manages to sport some handy features like auto-resetting work cycles each day, intelligently stopping a cycle if it’s paused too long, showing its status on the dock, and continuing to work in the background when the window is closed.

I use this one frequently while working and appreciate the combination of simplicity and attention to detail.

Notes-Up

Another app by Felipe Escoto, Notes-Up is a handy note-taking app. It has all the features you need: multiple notebooks that support multiple pages, Markdown support for rapid writing, PDF export with beautiful default elementary-inspired styling, and deep content search. Fun fact: I wrote this post in Notes-Up before pasting it over to Medium. :)
