- image sorting
|
|
- will affect:
|
|
- promote
|
|
- demote
|
|
- shift up
|
|
- shift down
|
|
- ribbon merging
|
|
- add promote/demote events (to attach structure editors)...
|
|
- add real images...
|
|
- make all the code relative to the current selection (multiple instances on a page support)
|
|
- make this into a jquery plugin...
|
|
- add dynamic loading and unloading for very large sets...
|
|
- gesture support...
|
|
|
|
- first stage refactoring:
|
|
- merge almost identical functions...
|
|
|
|
- multiple groups to promote/demote
|
|
ways to go:
|
|
- promote/demote and tag
|
|
|
|
ISSUES:
|
|
- jumping on focus up/down...
|
|
- demoting a first element (a ribbon is created) positions the field incorrectly (see demoteImage() for details)...
