Thanks for this, I like it.  
The proposal's style is as clean and polished as other *state of the art* marketplaces; here are some screenshots:

**Apple**

**Google**

**Microsoft**

**Mozilla**

*On your proposal I would add:*

**Authors**: I like what Mozilla does, Author should be displayed.   
**Votes**: we don't have number of downloads or shiny stars. Votes number is our rating system and it's an useful data for a potential user.

*What else?*  

It would be cool to have the possibility to browse the apps per categories and to order them by filters like  **Popular|Recently added|Recently updated**.  
 I'm aware that you don't want to customize it too much to avoid to fork the SE codebase; anyway those are my suggestions.
