Hi! Nice to hear that you’ve made some modifications to the documentation. I don’t have that critical about the documentation other than that the demo site could an index so you don’t have to scroll back and forth looking what you could do.
The help tool that gives you the shortcode and a preview is great and helps a lot (even though it’s emptied every time you exit the plugin settings)! I’d like a bit more help/info texts on each attribute/attribute option. For example Table in cell(s). What does it do? Download button. You might feel that it’s pretty straight forward, but a little text saying (“Adds a download button below the table for the user/visitor. Exports it in .csv”) goes a long way to make it more comfortable for all plugin users.
I don’t if it’s viable to add a functionality so that you could paste your own shortcode text in the shortcode box (in the plugin settings), not just just copy it. Then you wouldn’t have to add the info one by one to the attributes inputs.
If you want to be fancy about it, you could do so that when the user adds their shortcode in to the shortcode box, it would update/fill the attribute options accordingly.
