To change the language of the instructions
Yes, you just have to replace a couple of images after export.
In the assets/images/ directory, you'll find a few files the start with add_to_home_ and non_.
Simply replace those images with ones you've created. You only have to replace the ones that are relevant to your format (e.g., "add_to_home_ipad.png" and "non_ipad.png" for an iPad app).
To replace the text in the email message
Create a new .js file, insert something like the text below, and attach it in the Resources section of your in5 dialog:
webAppEmailSubject = 'Way too awesome {deviceName} Web App your should check out';
webAppEmailBody = 'Get this on your {deviceName} by visiting: ';
Note that {deviceName} (case-sensitive) will be replace dynamically with the appropriate device name (e.g., "iPad").
This is supported starting in version 2.8.6.
