Commenting on individual item

[izaslavsky]

This is an often requested feature.

When adding a comment, it would be great if the user has an option to comment on either pattern, or individual item (if there is an active item). It could be radio buttons on the comments form (if there is an active item).

If it is an individual item, then the graphics would reflect that item (showing its icon or image). It should also include item's #name and #href if present. The rest of the context (current variable and filters) would be also shown.

We may want to precede annotation names with p: (for pattern), i: (for item), g: (for group).

Grouping would be done later. The idea is that users should be able to form a group of items by manually selecting them into this group, then apply some operations to them (annotate, save, eventually forma a secondary variable from it, etc.)

could be a pointer to an image for the thumbnail in the annotation

Radio button:

• Comment on the active item (
• Comment on the pattern

We would need to add "Annotation type" and "Item ID" to the database.
Eventually, find annotations associated with an item
We may also find item annotations associated with a pattern as defined by filters and sort variable

this could be done after #85.
But could be also done independently, because fewer mouse clicks for the user to just comment on an active item
