Prestashop 9 - lacking functions?

[Ronnie79]

We are now running a Magento 1.9 webshop but are now seeking a more modern plattform, now just started trying out Prestashop 9.

Looking at the catalog there seems to be some basic functions that we really miss:

1. Isn’t it possible to see the category tree apart from when we are editing a category? I can’t even see which categories that has sub categories without having to click on the, 

2. Can’t seem to find a way to add products in a category when editing a category. Instead it seems I have to edit every product to add it one by one to add it in a category. As a last resort export a CSV, then edit and then import it. Is there any less time consuming ways, ticking boxes or drag-drop?

3. How can I add a combination to existing products? For example if some products later on will be available with options.

4. Is it possible to export products with all combinations, attributes and features? I can't even find how to export combinations separately, only how to import them...

Am I doing something wrong or half blind? 🤣Or Is there a way to get these functions without an expensive module?
