Marketplace MVC Refine

[debuggy]

Introduction

Refine the marketplace MVC design, improve the willingnes of user to use the marketplace.

Issues / Motivations

1. View: the list view needs to update:
   • the item card has too much blank space
   • the filter and sort functions is not enough
2. Model:
   • Item should have richer categories to select and filter
   • User could add tags for items
   • Item should have statistics such as download count and score

Proposals / Solutions

1. View: Make the layout view like huggingface

• remove item icon or shrink it P0
• remove summary in item card, only show update time and download count P0
• when name is too long, use ... and hover to display full name
  
• add sort button based on time, alphabet and most downloads
  
• split list view into two sections: public official templates and my templates, each section only show part of its items.
• pagination
• add categories filters: types, tasks(mnist, imagenet), frameworks(tensorflow, pytorch) and custom tags

2. Model: add additional info in market item

• custom tags: add tag, remove tag, edit tag
• categories: select preset categories when creating or editing item, such as mnist, imagenet, tensorflow, pytorch
• add statistics: download count and score (5point)
• user can give a score to item, the overall score of items is the average scores. the score each user give will be recorded.
  or only star it: favorite.
