A remark is simply a <?xxe-remark>
processing-instruction nicely rendered as a balloon in the styled view.
This balloon contains the first two letters of the username (login) of the author of the remark.
This balloon is given a random background color, which is specific to the author of the remark. For example, the color of all the remarks created by user hussein
will always be green, but there is no way for user hussein
to choose the color of his own remarks.
Hovering the mouse over this balloon displays the contents of the remark in a tooltip.
Double-clicking on this balloon displays a remark editor. Which remark editor is displayed depends on whether this editor is used to create a new remark or to reply to/modify an existing remark.
If a remark is explicitly selected or if the caret is contained in a remark, display the remark editor #2 which lets the user reply to a remark made by another user or modify her/his own remark or delete it.
Otherwise display the remark editor #1 in order to create a new remark. The new remark is inserted before the explicit selection if any, or at caret position otherwise.
Delete explicitly selected remark, if any. Otherwise if the caret is contained in a remark, delete this remark.
Delete all remarks.
Select preceding remark, if any.
Select following remark, if any.
