Categories and favs in launcher and marketplace

Hi guys, I have the suggestion which you can read at the title.
On one hand, I would like to create my own categories and make diffent groups for all the stuff that you give us and we buy every month. Sometimes I want to add for example some particles to a project but Its hard to find them because my paragon collection its very big.
On the other hand, sometimes I find, for example, a nice prop on the marketplace and If I want to see it again in the future, I must to navigate a lot until I find it (when I find it). Besides, probably, we want to get notifications about discounts of our favoriture marketplace stuff.

Thank you in advance.
