I feel like this app would benefit massively from the touch of an actual designer rather than using default bootstrap. When you are trying to write, you want a minimal, elegant, and non-distracting interface, and those tacky and jarring glossy buttons really throw me off.

I love the app though! If you can afford a couple hours of a designer's time (it's a simple interface, wouldn't take too much), I feel like the benefits would be huge. If you want my help with this, feel free to reach out, but I'm sure any designer would be glad to do it : )
