Looks like a great service. Just tried the CMS and it works beautifully; much better than the only other similar CMS I've tried (CushyCMS–which requires SFTP).
Perhaps a niche request, but are there any plans to add HTTP basic access authentication to select pages? I'm currently running a super simple static site for a research group, and I need a way to make a semi-private web page. Nothing properly 'secure' but more a method to prevent casual snooping. (I could set up my own web server, but I need to set up a website/system that other people are still able to look after once I leave.)
