Fixes and other issues
======================
- Verify the code to fix [issue 25](https://github.com/wilkelab/cowplot/issues/25)


Ideas for further development
=============================
- add more finegrained formatting options to plot_grid, e.g., per-plot x and y offsets, label colors & fonts, etc.
- make a theme for individual plots and one for grouped plots (and one for faceted plots?), make sure that all default settings work well together.
