link to tasks

i would like if

• i could link to specific tasks within a page
  • tasks automatically get a '#' url heading?
  • if each task getting a heading is too much maybe each list within a page could get a heading?
  • not sure how to make links/embeds that can handle changes to task description or number of tasks in the list.
    • not a problem in auto-generated indexes
    • linking in pages or externally, it poses some challenges.
• the tasks index would open to the exact task on-click
  • configurable to disable that if people don't want that?
  • configurable to open in new page?
  • would make the appearance of 'interactivity' actually do something until Interactive behaviour via PureScript #84 allows for other possibilities

in short term i may look at making my task index open the page in general on-click so at least it doesn't do nothing. in documents with large task lists, needing to scroll up-up-up until you find the heading is a bit annoying. an alternate to making the whole thing clickable i guess, would be to put the page name right-aligned on each task as a link.
