# TODO

# CURRENT (row filtering)
# CURRENT

1. [TODO] - Whens scrolled to the right and we update data, it doesn't re-render the rows. Only the left-most ones...
1. [BUG] - Rows change odd/even class if we add data and the grid is scrolled down... This is because the size of the data-set is changing, I think.
1. [TODO] - Change the deleted row check to use for newInN() instead of forEach().
<!-- 1. [TODO] - Allow identity function for row data, rather than using $$hashKey. -->
1. [TODO] - Check out using grunt-jscs-checker for js style checks

1. [TODO] - Move row filtering to feature module.

1. [TODO] - Make 'No Rows' message i18n
1. [BUG] - i18n causes an exception if a given value is not present.

1. [TODO] - Add handling for sorting null values with columnDef sortingAlgorithm (PR #940)
1. [TODO] - Currently uiGridColumnMenu uses i18n to create the menu item text on link. If the language is changed, they won't update because they're not bound...

# Grid Menu

1. [TODO] - Add "master" grid menu that overlays the whole grid when open (should have a decent-size padding that leaves and overlay with high opacity).
1. [TODO] - Make a master grid menu button using the font-awesome menu icon (add to fontello conf) that lives... somewhere... that won't move when columns scroll...

# Cleanup

1. [TODO] - Rename tutorials so they're consistent
1. [TODO] - Re-order tutorials
1. [TODO] - Build a tutorial index page.
1. [TODO] - Remove commented-out dumps from gridUtil
1. [TODO] - Rename gridUtil to uiGridUtil
1. [TODO] - Rename GridUtil in uiGridBody to gridUtil or the above
