# TODO
List of TODO items for Caravel
## Important
* **Getting proper JS testing:** unit tests on the Python side are pretty
solid, but now we need a test suite for the JS part of the site,
testing all the ajax-type calls
* **Viz Plugins:** Allow people to define and share visualization plugins.
ideally one would only need to drop in a set of files in a folder and
Caravel would discover and expose the plugins
## Features
* **Dashboard URL filters:** `{dash_url}#fltin__fieldname__value1,value2`
* **Default slice:** choose a default slice for the dataset instead of
default endpoint
* **Widget sets / chart grids:** a way to have all charts support making
a series of charts and putting them in a grid. The same way that you
can groupby for series, you could chart by. The form field set would be
common and use a single field to "grid by", a limit number of chart as
an N * N grid size.
* **Advanced dashboard configuration:** currently you can define which
slices in a dashboard are immune to filtering.
* **Annotations layers:** allow for people to maintain data annotations,
attached to a layer and time range. These layers can be added on top of
some visualizations as annotations. An example of a layer might be
"holidays" or "site outages", ...
* **Slack integration** - TBD
* **Comments:** allow for people to comment on slices and dashes
