This is a TO DO document for the =Uize.Widget.TableSort= module.

- should support headings with linebreaks (when headings have linebreaks, the tooltips for column values don't display well)
- update data sorting algorithm to be efficient (not bubble sort). Perhaps there's a way to use the built in sort, if the array being sorted is an array of objects combining the value and original column index, with a custom sort function that performs the comparison on the value. This could avoid using the current sortMap approach, which involves more swapping.

MUST HAVE

- CSS styles that can be specified for the sort order (rather than simply the headingLitClass property)
- support different combinations of over/lit classes

DESIRABLE

- a way to implement highlight states without the user having to specify classes
- for numbers with units suffixes, support metric unit canonicalization (so, one could have "2cm" and "1m" in a column, and sorting would do the right thing)
- extensible system for registering sort handlers for different types of column data
- support multiple table sections, with sorting discrete to each group
- support for mixed data types in columns
- support for form fields (sorting, and retaining values to deal with stupid IE bug)

PERHAPS

- ability to have class values for rows persist regardless of changed row order (useful for tables that alternate classes for readability)
- support for non-sortable columns (e.g. a column in a table containing only pictures)
- failure modes for complex tables that aren't suited to sorting (e.g. columns with rowspans)
- a way for the user to restore the table to its original state (unsort?)
