Testing upgrade V3 to V4 bugs report

First thank you for the new version it is simply to fall in love with.
I did some tests , migrating 70k plus users , wtn ok with few bugs on db rebuild but before that , i was surprised to see that there is no pagination in shopping cart . I have 40 products in 1 category and the list is just huge to be presented like that. I maybee missed a setting.

Also noticed that cart has no function to update quantity and clicking twice on same product just adds it in once so again no quant change. To sum down here are few things I thought that are inand some bugs

1. Admin products display list shows only 10 products , cant find setting for more than 10

2. Aded 17 products in category , when using filter in admin it shows 0 when using filter in frontend it shows only 10

3. FIlter seems like has wrong name assigned to category , example
Cat1 10 products
Cat2 3 products

4. I select Cat2 but shows products from Cat1
Select Cat1 shows all products (115)

5. Category description is not displayed in frontend , In admin on save and click edit again it is not present anymore ( using FF latest )

6. Would be nice to see category that product belongs to in admin products column. Right now is title-billing-sort-action
7. Is Joomla plugin ready for v4 and what joomla versions?
