|
|
* This is a complete remake of the original link tool. |
|
10
|
|
|
* New features: |
|
11
|
|
|
* - Organize links into categories; |
|
12
|
|
|
* - favorites/bookmarks interface; |
|
13
|
|
|
* - move links up/down within a category; |
|
14
|
|
|
* - move categories up/down; |
|
15
|
|
|
* - expand/collapse all categories; |
|
16
|
|
|
* - add link to 'root' category => category-less link is always visible. |
