sidenotesplus
Sidenotesplus is a comprehensive package for placing labeled or referenced notes, temporary alerts, bibliography references, figures and tables into the margin. Marginals can be either floated or at fixed positions relative to the text. Twoside symmetry is preserved. For BibLaTeX users, macros for side references are provided.
Three margin styles are provided. Two-page symmetric layouts either as (i) Ragged outer with note reverences in the margin separator or (ii) justified with last line ragged outer. And (iii) a classic look, justified with last line ragged right and note reference to the left of the note, but two-page symmetry is lost.
The command \sidenote mimics the \footnote command and provides labelled (numbers, alphabetic, roman) references. However, un-numbered and custom symbols can also be specified.
Temporary sidealerts are rendered only if the package option alerton is specified. Alerts are useful as to do reminders during document development.
Furthermore, captions for figures and tables can also be placed into margin. Also, full width environments for figures, tables and text are provided. The text environment can be partially widened, suitable if that extra space for an equation is required. [ctan.org/pkg/sidenotesplus]
Sidenotesplus是一个综合包，用于将标记或引用的注释、临时提醒、文献引用、图形和表格放置在页边。在边缘中的内容可以是浮动的或相对于文本的固定位置。保留两面对称。对于BibLaTeX用户，提供了用于侧面引用的宏。
提供三种边距样式。两页对称布局可选：(i) 边缘不整齐，带有边界分隔符中的注释引用，或(ii) 对齐，最后一行边缘不整齐；还有(iii) 经典风格，对齐，最后一行右边不整齐，注释引用在注释左侧，但失去了两页对称。
命令\sidenote模仿\footnote命令，提供标记（数字、字母、罗马数字）引用。然而，也可以指定无编号和自定义符号。
只有在指定包选项alerton时，临时侧面提醒才会显示。提醒在文档开发过程中非常有用，可以作为待办事项提醒。
此外，对于图形和表格，标题也可以放置在边缘中。同时，也提供了图形、表格和文本的全宽环境。如果需要额外空间放置公式，文本环境可以部分扩展。 [ctan.org/pkg/sidenotesplus]
