Agile SCRUM for Trello boards

Description

Agile SCRUM for Trello boards gives super-powers to your Trello boards by enabling SCRUM features:

★ STORY POINTS: Set Story Points for Trello Cards
★ TIME SPENT: Set time spent on tasks.
★ TAGS: Group Cards into tags, User Stories or projects, these are colored automagically to save you time.
★ PROGRESS BARS: Visualize your Sprint progress instantly with unobtrusive background progress bars on both cards and lists.
★ HEADER SEPARATORS: Use header separators to group cards inside lists.
★ VISUAL AIDS: Cards with more Story Points have a slightly increased font size so you can distinguish bigger from smaller tasks at a glance.

Instructions
―――――――――――――――――――
There's no need to set up anything! This extension is made to be simple, install it and start giving super powers to your Trello.

Add Story Points to a card by typing the number in parenthesis:
"(3) Design new homepage header"

Track time spent on each card:
"(1/3) Design new homepage header"

Assign a card to a Project by writing it in square braquets:
"[dev] Implement Ads in footer"

Create a Header Separator by creating a new card with three asterisks at the start and end:
"*** Sprint 3 ***"

You can add as many tags as needed. Tags will be colored automatically in a random color.

Both Story Points and Tags can be defined anywhere in the card's text, it's usually best to add them at the start so it's easier to read.

At the top right of the Lists and Cards you can see how many story points have been completed and how many there are in total.
