Content Store improvement ideas

I have few improvement ideas for Content Store:

1. Filters
1.1. Currently users are able to select multiple filters from multiple entities. If two entity types are active, eg. Items and Resources, and you select one filter from Item and one from Resources > search result is empty. Somehow it doesn't work as expected, and it is super confusing. You should change the logic either so that if you use filters from multiple entities, filters don't exlude each other OR you can't use filters from different entities at the same time.
1.2. It would be good if you could affect/change the order of the filters. And how user could even know, which filters are for Items and which for Resources, when both types are selected?

1.3. It would be good if you have a button to clear all the filters.

2. It would be good if you could send an email and share your cart directly with the customer from Content Store.
