Very good app, few things could make it great

This app does what you need. It could stand to have some UX improvements:

1) Drag and drop of image files.
2) Numeric specification of font-sizes instead of clicking several times
3) Auto-naming convention for ease of export, with file overwrite option.

This is definitely a clean, very mac-like meme generator, though.
