Now displays readable labels for post thumbnails in latest on github. Please let me know if you see any problems.
Sorry for my late answer but when i try to save settings i’ve got a PHP Fatal Error

That’s a different plugin: ‘manual-image-crop’ and not ‘post-thumbnail-editor’.
When you browse to the settings page after, does it appear that the settings actually saved?
If not, a workaround might be to disable the manual-image-crop plugin, change your settings (as this should be a one time — or not very often anyways — and then re-enable the manual-image-crop plugin.
