Settings are not accessible for visual impaired

Hello,

I use a screen reader, NVDA, as I am blind. I managed to get the plugin to work, but if I go into the settings, the various options are not made up of normal checkboxes or radio buttons or combo boxes. I have no idea what you use, but unfortunately for me it is not possible to understand whether the various functions are active or deactivated. The only accessible parameter is the feed update one, because it is a normal editing field and reads 720. Could you please make the interface accessible to screen readers? Unfortunately this is one of the very few plugins that is not accessible… Thank you.
