@ciccio-kit I accidentally closed the last PR for this, so to answer your questions:

I might be misreading the flow here, but aren't these settings abilities now getting registered through two paths? This filter seems to call register_abilities() on the base section (keyed kit/general-), and ConvertKit_MCP::register_settings_abilities() also adds them (keyed kit/settings-general-). Since both instances return the same get_name(), I think wp_register_ability() could end up being called twice with the same name, but I'm not 100% sure how the dedup works. Could you double-check whether that is the case?

Correct and resolved.

is float a valid type or should this be number instead?

Changed to number which is valid.
