First, this forum is missing a “feature request” or “suggestions” topic!
Most open source software forums do have such a section, where also other users can rate up (or down) feature requests.
I think this would be good for Grav and its developers and users.
Now to my suggestion of interoperability:
Interoperability is not only a more and more important issue in European competition politics, but it’s also an important part of good software (which also doesn’t need to bind users by force).
I’ve got many years of experience in online marketing and website development, and one of the first things I’m checking out when deciding for an important new software (like a CMS) is whether I can easily import and export data (in a standardized format).
This is extremely important when it comes to independence, transferability and backups. And this is what I was missing when checking out Grav.
I wouldn’t have used Grav for an important project, therefore, but still gave it a try with a smaller project (and found / find it very nice! A really fresh and easy alternative to the usual Wordpress, not needing a vulnerable database…).
Still, I think with a good and easy-to-use native data import and export system (which should also reliably work for larger websites / huge amount of data!) Grav could attract many more (advanced) users!
And even for my currently small projects, I would have a better feeling if I were able to export and transfer data easily anytime (and potentially import it into other systems, like for ex. Wordpress, if needed or wanted for whatever reason, like for an essential function that’s missing in Grav, or because of a client’s wish).
Thanks for your consideration, and I hope my feedback is helpful!
